23 Feb, 2018

Curling is a deceptively engrossing sport with some unique physics among Winter Olympic events. Athletes slide 19kg granite stones at a target 28 meters away. Along the way, teammates sweep the pebbled ice with brooms, melting it with frictional heating to help the stone slide further. The underside of the stones is concave, so they only touch the ice along a narrow ring. Researchers think roughness in the leading edge of the sliding stone cuts into the ice, leaving scratches that the trailing edge tries to follow. This is what causes the stone’s trajectory to curl. By melting the ice, sweeping also prevents curling, so competitors must know exactly when and how much to sweep. Ice conditions shift throughout a match, and the best players can read the ice to keep their stones where they want them. (Image credit: AP; W. Zhao/GettyImages)

22 Feb, 2018

Cross-country skiing, also known as Nordic skiing, is a part of many longstanding disciplines in the Winter Games. Unlike downhill skiing, cross-country events typically involve mass starts, which allow athletes to interact, using one another for pacing and tactics. Drafting can be a valuable method to save energy and reduce drag. A following skier sees a 25% drag reduction while drafting; the lead skier gets about a 3% reduction in drag compared to skiing solo. Competitors usually wear tight-fitting suits to minimize drag, but unlike speedskating, for example, cross-country skiers don’t get much benefit from roughened surfaces and impermeable fabrics. Typical race speeds are 4 - 9 m/s, and most of these high-tech fabrics don’t provide tangible benefits until higher speeds. (Image credit: Reuters/S. Karpukhin, US Biathlon, GettyImages/Q. Rooney)

► When it comes to winter sports, not all ice is created equal....
21 Feb, 2018

When it comes to winter sports, not all ice is created equal. Every discipline has its own standards for the ideal temperature and density of ice, which makes venue construction and maintenance a special challenge. Figure skating, for example, requires softer ice to cushion athletes’ landings, whereas short-track speed skating values dense, smooth ice for racing. The Gangneung Ice Arena hosts both and can transition between them in under 3 hours. Gangneung Oval hosts long-track speed skating and makes its ice layer by layer, spraying hot, purified water onto the rink. This builds up a particularly dense and therefore smooth ice.

The toughest sport in terms of ice conditions is curling, which requires a finely pebbled ice surface for the stones to slide on. Forming those tiny crystals on the ice sheet can only be done at precise temperature and humidity conditions. This is a particular challenge for Gangneung Curling Center due to its coastal location. To keep the temperature and humidity under control at full crowd capacity, officials even went so far as to replace all the lighting at the facility with LEDs!

20 Feb, 2018

In bobsleigh, two- and four-person teams compete across four runs down an ice track. The shortest cumulative time wins, and since typical runs are separated by hundredths of a second, teams look for any advantage that helps them shave time. The size, weight, and components of a sled are restricted by federation rules; for example, teams cannot use vortex generators to improve their aerodynamics. Instead bobsledders work with companies like BMW, McLaren, and Ferrari to engineer their sleds. Both computational fluid dynamics and wind tunnel tests with the actual team in the sled are used to make each sled as aerodynamic as possible. (Image credit: IOC, Gillette World Sports, source)

19 Feb, 2018

These days artificial snow-making is a standard practice for ski resorts, allowing them to jump-start the early part of the season. Snow guns continuously spray a mixture of cold water and particulates 5 or more meters in the air to generate artificial snow. The tiny droplet size helps the water freeze faster and the particles provide nucleation sites for snow crystals to form. As with natural snow, the shape and consistency of the snow depends on humidity and temperature conditions. Pyeongchang is generally cold and dry, so even the artificial snow there tends to be similar to snow in the Colorado Rockies. Recreational skiers tend to look down on artificial snow, but Olympic course designers actually prefer it. With artificial snow, they can control every aspect of an alpine course. For them, natural snowfall is a disruption that puts their design at risk. (Video credit: Reactions/American Chemical Society)

16 Feb, 2018

Four years ago in Sochi, Under Armour’s suits for the U.S. speedskating team took a lot of flak after the team failed to medal. The company defended the physics and engineering of their suits, and an internal audit of the speedskating program ultimately placed blame on flaws in their training regimen, unfamiliarity with the new suits, and overconfidence.

This time around Under Armour has taken a more hands-on approach with the team, helping with training regimens in addition to providing suits. Under Armour spent hundreds of hours testing the suits in Specialized’s wind tunnel, including testing many fabrics before settling on the slightly rough H1 fabric used in patches on the skater’s arms and legs. Like the previous suit’s dimpled design, the roughness of the fabric promotes turbulent flow near it. Because turbulent flow follows curved contours better than laminar flow does, air stays attached to the athlete for longer, thereby reducing their drag. The suit is also designed with asymmetric seams that help the athlete stay low and comfortable in the sport’s frequent left turns.

U.S. speedskaters have been competing in a version of the suits since last winter, ensuring that athletes are familiar with the equipment this time around. Whether the new suits and training program will pay off remains to be seen. After their disastrous experience in Sochi, both the team and the company are shy about setting expectations.

► Long-Necked Dinosaurs Succumb To CFD
14 Jul, 2017

It turns out that Computational Fluid Dynamics (CFD) has a key role to play in determining the behavior of long extinct creatures. In a previous, post we described a CFD study of parvancorina, and now Pernille Troelsen at Liverpool John Moore University is using CFD for insights into how long-necked plesiosaurs might have swum and hunted.

► CFD Provides Insight Into Mystery Fossils
23 Jun, 2017

Fossilized imprints of Parvancorina from over 500 million years ago have puzzled paleontologists for decades. What makes it difficult to infer their behavior is that Parvancorina have none of the familiar features we might expect of animals, e.g., limbs, mouth. In an attempt to shed some light on how Parvancorina might have interacted with their environment researchers have enlisted the help of Computational Fluid Dynamics (CFD).

► Active Aerodynamics on the Lamborghini Huracán Performante
3 May, 2017

Early on in the dash to develop ever faster racecars in the 1970s, aerodynamics, and specifically downforce, proved a revelation. Following on quickly from the initial passive downforce initiatives were active aerodynamic solutions. Only providing downforce when needed (i.e., cornering and braking) then reverting to a low drag configuration was an ideal protocol, but short lived due to rule changes in most motor sports (including Formula 1), which banned active aerodynamics. A recent exception to the rule is the highly regulated Drag Reduction System now used in F1. However, road-legal cars are not governed by such regulations and so we have the gloriously unregulated Lamborghini Huracán Performante.

And pressure equation will be not converged smoothly, I guess. What are your experience on the subject? What do you mean with not efficient? Somewhere else it has been suggested to use pressure tolerance 2 order of magnitude lower than velocity tolerance. Therefore, as I lower velocity tol, I must lower pressure tol as well. This was suggested as a "remedy" due to the higher difficulty on pressure eq to get convergence. On the contrary of what reported above, fvSchemes attached on the last post used a linear upwind scheme... Does it applies with tet mesh or with hea as well? Hope to get it when published! Therefore, my next steps are: use relTol 0.05 on p -> BTW, why not efficient? lower U tol use first order everywhere. One more question: is this setup convergent, but not accurate? mad

Layers are not available with all meshing algorithms. Otherwise you just set your 2D and 1D meshing parameters the normal way. If you then submesh a face with different parameters (quadrangles for example) and this face has viscous layers, they should retain the structure of the face. Salome can grow very nice viscous layers, but there is a known bug in the current version 7.3.0 that crashed the layer algorithm at the start for me. It is fixed in 7.4.0 due to come out any time now I was told. Have a look, and I could put an example together for you if it helps. Regards, Eric
► Free YouTube Lessons for Applied CFD in Aerodynamics using ANSYS and OpenFOAM
9 Nov, 2017
I have decided to share in this Group a series of video Lessons I am making for a CFD course in Computational Aerodynamics at De Montfort University, Leicester, UK. The link for the play list is provided below:

6 Lessons already exists, and with in the next few months (weekly) new videos will be uploaded.
It will consist of
* Geometry Handling Techniques
* Structured Blocked Meshing approaches In ICEM CFD
* Unstructured Meshing approaches in ICEM CFD
* Introduction and Basic usage of OpenFOAM

Meshing will be carried out for simple airfoils, wings and also full scale aircrafts such as NASA CRM, DLR F6, F11, Fighter Configuration F16, General Transport Model and many more related geometries.

I hope this comes of use to the Fluid Dynamics Society. Even though it is specified course for Computational Aerodynamics it can be rapidly invoked in Meshing and CFD analysis of any other Geometries

► Rayleigh–Bénard Convection Using buoyantBoussinesqPimpleFoam
13 Jun, 2017

Here is an extremely simple simulation to set up that has a surprisingly beautiful output. In this post, we will simulation the classic Rayleigh–Bénard convection (see Wikipedia) in 3D using the buoyant solver, buoyantBoussinesqPimpleFoam.

buoyantBoussinesqPimpleFoam is a solver for buoyant, turbulent, incompressible flows. The incompressible part of the solver comes from the fact that it uses the Boussinesq approximation for buoyancy which is only suitable for flows with small density changes (aka incompressible). A good source for the equations in this solver is this blog post.

## Simulation Set-up

The basic set-up for this case is simple: a hot bottom surface, a cold top surface, either cyclic or zero-gradient sides, and some initial conditions.

For this example, I used the properties of water, I set the bottom plate at 373 K (don’t ask me why… I know it’s close to boiling point of water), and the top plate at 273 K. For this case, we will not use any turbulent modeling and will simply use a laminar model (this simply means there is only molecular viscosity, there are no simplifications applied to the equations).

### Geometry and Mesh

The geometry is shown below. As the geometry is so simple… I will not go over the blockMesh set up. The mesh discretization that I used was simplegrading (i.e. no inflation), with 200x200x50 cells.

### Constant

For this case, we will simulate water. The transportProperties file should look like:

transportModel Newtonian;

// Laminar viscosity
nu [0 2 -1 0 0 0 0] 1e-06;

// Thermal expansion coefficient
beta [0 0 0 -1 0 0 0] 0.000214;

// Reference temperature
TRef [0 0 0 1 0 0 0] 300;

// Laminar Prandtl number
Pr [0 0 0 0 0 0 0] 7.56;

// Turbulent Prandtl number (not used)
Prt [0 0 0 0 0 0 0] 0.7;

I don’t typically delete unused entries from dictionaries. This makes using previous simulations as templates much easier. Therefore note that the turbulent Prandtl number is in the dictionary but it is not used.

Selecting Reference Temperature TRef for buoyantBoussinesqPimpleFoam. To answer this recall that when the Boussinesq buoyancy approximation is used, the solver does not solve for the density. It solves the relative density using the linear function:

$\frac{\rho}{\rho_0}=1-\beta \left(T-T_0\right)$

Therefore, I think it makes sense that we should choose a temperature for $T_{ref}$ that is somewhere in the range of the simulation. Thus I chose Tref=300. Somewhere in the middle!

And the turbulenceProperties file is:

simulationType laminar;

RAS
{
RASModel laminar;

turbulence off;

printCoeffs off;
}

The g file tells the solver the acceleration due to gravity, as well as the direction:

dimensions [0 1 -2 0 0 0 0];
value (0 -9.81 0);

### Boundary Conditions

In the “zero” folder, we need the following files: p, p_rgh, T, U, and alphat (this file needs to be present… however it is not used given the laminar simulationType.

► Good Hardware Means Improved FlowSight Performance
18 Dec, 2017

In order to take full advantage of FlowSight, our advanced state-of-the-art postprocessor, it is essential that you have good hardware. In this blog, Stephen Sanchez, senior GUI developer, gives his two cents on how you can obtain improved FlowSight performance by following these hardware recommendations.

## Get a really good graphics card

We highly recommend that you start with a graphics card with at least 3GB of VRAM. This is especially important if you will be doing a lot of volume rendering. Volume rendering is an advanced capability of FlowSight that visualizes the details of a variable throughout the fluid domain, instead of just the iso-surface. This feature is quite insightful, but requires good hardware to be effectively used during post-processing.

Next, you should not use Intel integrated graphics as your primary graphics hardware. Much of FlowSight’s functionality does not work with this configuration, and as a result, we do not support Intel integrated graphics. FlowSight performs best when used with NVIDIA graphics cards, particularly the Quadro family. While high-end AMD cards should work, we have found that they are not as reliable as NVIDIA hardware and drivers, so we always recommend NVIDIA over AMD.

## Dual graphics cards on laptops – A simple but hidden solution

Many laptops now come with the ability to switch between a NVIDIA card and an Intel Integrated graphics card. It is important that you make sure FlowSight (as well FLOW-3D) is being launched with the NVIDIA card. Forcing your laptop to launch with the NVIDIA card can be done through the NVIDIA control panel.

We recommend that you check to make sure that your video driver is up-to-date. We have had reports of artifacts and display issues in FlowSight that have been easily resolved by simply updating the video driver. Keeping your video driver current is a good way to avoid such issues.

## RAM, RAM, RAM!

It is important to be aware of memory requirements, as insufficient memory can lead to as high as a 10x performance decrease! The amount of RAM needed depends on a number of factors, particularly the size of your simulation. In order to provide users with the most flexibility, we have the following RAM recommendations based on simulation size:

• Extra-large (200 million+ cells): At least 128GB
• Large (Between 60-150 million cells): 64-128GB
• Medium (Between 30-60 million cells): 32-64GB
• Small (30 million cells and below): At least 32GB

However, you should always get the most RAM as you can, irrespective of the problem size in order to maximize flexibility and ensure the smoothest user experience.

In a later blog we’ll expand on how to get the most out of FlowSight by discussing core features that are typically the most time and resource intensive, and how they can be used more efficiently.

► White Paper: Formal Verification: Not Just for Control Paths
22 Feb, 2018

Whether it is a full formal verification environment, or a complementary piece to an existing testbench targeting critical or difficult to reach functionality, the secret to enabling datapath verification is managing state space and constraining dynamically sized transactions. An RTL based formal testbench responsible for capturing and simplifying transactions holds and deconstructs the static pieces of the transaction. A synthesizable relationship can then be formed between the static and dynamic packet components and state space is reduced via a collection of assumptions built around the packet defining RTL.

► White Paper: Understanding The UPF Power Domain and Domain Boundary
22 Feb, 2018

This paper focuses on the fundamental construct of UPF and its methodologies for defining and distinguishing a power domain and domain boundary. The mainstream techniques adopted today, as shown in this paper, are mostly based on design type and the complexity demands for system-on-chip, ASIC, microcontroller unit, or processor core design implementations.

► White Paper: Tools + services accelerate automotive electrical design
19 Feb, 2018

Scott Majdecki and Andrew Macleod explain why services offered in conjunction with design tools matter more than ever in automotive E/E design. Indeed it’s no stretch to say that advanced automotive design software combined with proven deployment services is the surest path to success. Take out that services expertise and the path suddenly gets that much longer and more uncertain, precisely at the moment when falling behind will be more costly than ever. That’s because the industry’s well-documented evolution in the direction of electrification, autonomy, services and ride sharing, together represent one of the most lucrative business opportunities in history.

► Appending Data to Tecplot 360 SZL Files
16 Feb, 2018
“Time is an Illusion.” ― Albert Einstein

High fidelity CFD solvers are generally iterative in nature. They move the solution incrementally forward in time (or pseudo time for steady-state solutions) computing each new solution based on the previous solution. CFD engineers often write a snapshot of the solutions at periodic time steps so that they can follow its progress.

CFD engineers want to verify that:

• The boundary conditions are behaving as expected.
• The solutions is stable.
• They want to do this while the solver is still running.

The latest improvements to the TecIO library make this much easier!

### Previous Limitations

Earlier versions of TecIO had limitations when writing out a sequence of time steps to a SZL (.szplt) file. It worked OK if each time step was written to a separate file; but appending data to the same file caused it to cache a large amount data in memory. In addition, writing to separate files limited the use of variable sharing (which minimizes file size by sharing, for example, a common set of grid coordinates).

On many high-performance computing systems, the total number of files is limited. On these systems, appending all time steps is the preferred option since it reduces the number of files created.

As of Tecplot 360 2017 Release 3 (November 2017), all of these limitations have been solved!

### New TecIO Capabilities: Appending Data to SZL Files

The 2017 R3 version of TecIO (released November 2017) has a new function, TECFLUSH142, that will write the currently cached TecIO data to a set of intermediate files. These files are then recombined into a single SZL file when TECEND142 is called to complete the write.

This accomplishes three things:

1. It eliminates the excessive memory usage of previous TecIO versions when writing multiple time steps.
2. It allows the sharing of variables across multiple time steps. This is commonly used with unchanging grids to share the same set of grid coordinates across all time steps.
3. It allows the user to view the data before all time-steps have been written to the file.

Item 3 is a new capability in TecIO 2017 Release 3. It is accomplished using a shell utility called szcombine, which reassembles the temporary files into a single SZL file.

With these new capabilities, TecIO is far more usable for writing multiple time steps than it has been in the past. Give it a try!

► Top 3 Reasons to Post-Process COMSOL® Results with Tecplot 360
3 Jan, 2018

Having a reliable, accurate, flexible and easy-to-use method to post process your results is key to effectively analyzing CFD, other simulation and test data results.

Tecplot 360 is a suite of CFD visualization and analysis tools that can handle large data sets, automate workflows and visualize parametric results.

## Why Visualize and Analyze Your Data With Tecplot 360?

1. ### Load Simulation And Test Data From Many Different Sources

If you aggregate data from multiple simulation sources, in addition to test data, you need the ability to load dozens of file types, as well as to cohesively view and compare all of your results. With Tecplot 360, organizing data into one or many frames is easy, intuitive and quick.

Powerful visualization options give you the ability to scale, sort and overlay images and data. Extracting data from 2D and 3D visualizations to match with 1D test data is fast and can be easily automated.

Read Details In The Tecplot 360 Datasheet (PDF) »

2. ### Have Complete Control Over Your Plots

Communicating your results with professional, report-quality plots means you need the right format for the right publication – whether for a printed report, a presentation or a website. You will also want control over every aspect of the way your plot looks.

With Tecplot 360, you can output plots as raster and vector images, and in multiple video formats for animations. You can also:

• Annotate with LaTeX fonts
• Gain precise control over axes, plot backgrounds, labels, and legends
• Overlay multiple contour lines and variables on the same plot
• Export high-quality PNG, PostScript or EPS

You will not find a more flexible post-processor.

3. ### Analyze Your Results Quickly And Accurately

Creating high-fidelity models of complicated applied physics interactions mean lots of data to handle. You need a tool that can reduce time-to-first-image and all-around processing time. If you are working on a laptop or other mid-tier computer, running out of RAM and huge file sizes can be a major headache.

Tecplot 360’s SZL file format loads and processes data faster, uses less memory and produces smaller file sizes. Integrating software, like MATLAB, into common workflows is a requirement for engineering tools today. Tecplot 360 is extensible through our Python API and through the Macro language.

Whether you are working with CFD, other simulation or test data, you need accurate results, robust analyses and seamless communication. Tecplot 360’s suite of visualization and analysis tools have unique features that help you explore large data sets from multiple simulations, compare results and evaluate overall system performance.

► New Ways to Visualize Increasingly Complex and Unsteady Data
21 Dec, 2017

As we look forward to 2018 and beyond we’re excited to take part in an industry that never rests and is never satisfied. We’re eager to bring new ways to visualize increasingly complex and unsteady data, and provide new analysis features, while maintaining the Tecplot promises of giving engineers complete control over their output, fast post-processing speed, report-quality XY, 2D and 3D plots, and excellent stability, service and support.

### A Look Back at the Porsche 956

On the first day of my first aeronautical engineering job after graduate school, I opened my desk drawer and found a small package of 35mm Kodachrome slides dating back to the early 1980’s (it was an old desk). The image below, likely pre-dating Tecplot entirely, is from those slides. Racing fans will know that it’s a model of a Porsche 956, a famous beast of a racecar from the Group C era of endurance motorsports.

Flow simulation of a Porsche 956, circa 1982

Fluids experts will infer that it’s not even a “real” CFD solution. It’s from a potential flow code, and at that time, this simulation was likely run on a Cray X-MP and took hours, if not days, to complete. As I write in the waning days of 2017, I think of this image frequently and ponder how far our industry has come over the ensuing 35 years, and specifically how far Tecplot has come in 2017.

### Visualize Increasingly Complex and Unsteady Data

In January we released Tecplot 360 2017 R1, with PyTecplot and SZL Server, and made Chorus available to all Tecplot 360 clients with active maintenance. This was the biggest change to Tecplot software in the past several years. Throughout the year we’ve added to PyTecplot, making it possible to control the Tecplot GUI and streamline workflows.

It has been a big push by everyone at Tecplot, and the reason for this effort is clear: we don’t live in 1985 anymore and our clients need better tools with enhanced capabilities. Engineers create tens or hundreds of gigs of data overnight, both in the form of hundreds or thousands of simulations, and also extremely large simulations.

That isolated panel method solution is largely history, and in its place are ensembles that you can analyze in Chorus, billion-cell runs you can visualize with SZL (and remotely with SZL Server), and data of all forms that can be automated with PyTecplot to meet the increased expectations placed on engineers everywhere.

A big thank you to all our users and supporters for a great 2017, and stay tuned for much more.

► Quickie: Topcon acquires ClearEdge3D to move into software
22 Feb, 2018

Topcon announced earlier this week that it has acquired ClearEdge3D, a maker of 3D modeling and construction verification software. Unless you’re into AECish topics, you may not have heard of Topcon. Topcon is a Japanese company that makes positioning instruments such as survey stations, laser scanners and similar gear (among other things that aren’t relevant here). ClearEdge3D is a US software and services company best known for its EdgeWise and Verity brands. EdgeWise isn’t BIM (building information management), but ties into BIM models and workflows by manipulating laser scan point clouds to create objects for use in a BIM product like Autodesk’s Revit. By scanning an existing asset and then feeding that directly into BIM, the CAD modeling step in an AEC project can be significantly shortened. And since one of Topcon’s product lines is laser scanners …. you can see where this is going.

Verity, ClearEdge3D’s other main product, compares a point cloud to design or fabrication models, identifying anything that doesn’t match –maybe floors that aren’t level or items that have been installed in the wrong place. This used to be done manually, by humans who walked a construction site to make these comparisons. Verity automates the task, and laser scans remove any ambiguity or personal interpretation.

Why am I telling you this? Because whether you’re in AEC or not, this is about data. About using laser scans, in this case, for as many things as humans can think of. And it’s about applying techniques like object recognition (does that cloud of points represent a door or a window?) to new areas. One can see this combination having application far beyond the construction site, as the BIM model moves through the lifecycle of that building. Want to move a wall? A laser scan of its construction can reveal exactly where the electrical lines are. Need to train someone in a dangerous task? Have them move through a BIM model to practice virtually.

It’s also about hardware plus software. ClearEdge3D has said that it plans to maintain its hardware agnostic view of the market, so not disadvantaging users of competing laser scanners. Topcon has said it doesn’t see any immediate changes to Verity or EdgeWise but one can theorize that they might be bundled with Topcon laser scanners in the future. It’s also about software margins: hardware is notoriously low-margin because each item has a fixed cost. Software is the opposite: with downloads, the first license bears all the cost of development and every other license is pure profit.

Financial details of the transaction weren’t released.

► 10 things: Digitalization at AVEVA World Conference, Houston edition
21 Feb, 2018

I spent the last week with AVEVA at its North American user conference. I haven’t attended one of these in years, mostly going to the international Summit events (here, here … search the site for more). The Summit is strategic; it’s about IT and economic trends, forces shaping the end-industries AVEVA addresses. The Conference has a bit of this but also very specific roadmap sessions, down to what’s in coming point releases. It was fun and interesting to hang with users and department managers — their interests are specific and often short-term.

The keynotes were focused on the theme of the event, digitalization. Yes, it’s hard to say, but it’s oh so important to consider. Tom Singer of Aker Solutions, Justin Weaver of Southern Company and Terje Maanum of Statoil spoke about how digitalization changes their enterprises. Aker, for example, creates template-based design concepts that enable them to quickly and accurately generate quotes and preliminary designs, and then feed directly into more detailed work if they win the contract. Southern Company is working to replace job boxes (the steel container in the title photo) full of paper drawings with boxes that contain touchscreen monitors to enable the same view and markup but also walkthroughs and other techniques designed to help trades better understand what they’re working on. Finally, Statoil is really impressive, managing all of the data on over 70 assets with a team of 8 people — but most gee-whizzy was the fact that this single-source concept leads to downstream technologies like augmented reality, which helped identify equipment that had been installed incorrectly. Statoil’s EPC was able to find and fix the problems before the plant commissioning, averting a disaster.

This kind of forward-looking technology use was present in all of the sessions I attended, whether on how to become an EPC 4.0 (a cute play on the whole Industry 4.0 thing) to how handover standards can and will change what and how we model. But there was some really detailed tactical stuff in the roadmaps, too, to show how AVEVA plans to move its products forward.

With this background, here are ten things I think I think about AVEVA World Conference, North America. In no particular order:

1. Unlike many of its peers, AVEVA invites prospects to this event. That’s very confident of the company, since no one can control who these prospects speak with or what they, therefore, learn. I sat with one gentleman who was interested in one of AVEVA’s lesser-known offerings and was surprised by the sheer size of the rest of the portfolio.
2. The elephant in the room, AVEVA’s merger with Schneider Electric’s software assets, wasn’t addressed all that much — the deal is about to close, likely on 1 March 2018. A new CEO starts this week. More than that, no one seems to know. But expectations are high and the excitement was real. As in Cambridge, people are looking forward to seeing what this much larger software company can do.
3. That much bigger product portfolio will address the entire life of a production plant, from front-end conceptual design via process simulation, through detailed design, operations and ultimately, into decommissioning. It takes the AVEVA toolset from short-term to lifecycle-long relevance — and many attendees are thinking about how that will change what they do.
4. Will they design differently if that model can/will be used in operations? There are systemic problems in the process industries that make that far from commonplace right now, but the greater scope of AVEVA’s offering has the potential to finally shift that — and the keynotes examples highlight why it’s such a good idea.
5. Many in the audience in Houston were tactical–users who needed to get a job done. In many cases, EPCs who use many if not all of the products on the market. They were there to talk to product managers about what’s in the next point releases — and told me that, in general, they’re happy with their AVEVA product(s) and that it stacks up well against the competition. They use whatever tools their clients specify and try to keep their skills sharp across the products.
6. AVEVA has taken a slow roll approach to cloud, reasoning that many of its users and projects are in areas where WiFi is uncertain or where security concerns prevent adoption. The company showcased partner Orinox, which offers a one-stop shop for cloud virtualization of AVEVA’s products. Joint customer Southern California Gas spoke about spinning up an AVEVA installation for a project in 2 weeks. They had more users than anticipated, which meant tapping into the flexibility of cloud licensing, using 1D, 2D and 3D products as well as incorporating laser scans into their workflow. it was ambitious and ultimately successful: the company plans to roll out its AVEVA cloud to more projects.
7. Another presentation in that same session could not have been more different — and showcases how AVEVA has been working to add cross-vertical products for longer than many people realize. Northwest Fabricators told how they transformed their business via AVEVA’s Fabtrol. They’re a 40,000 shop that cuts steel and welds pipe, serving customers on large and complex projects via Excel spreadsheets. Can you imagine? A 30 MB spreadsheet that opened so slowly, people were afraid to breathe while it did in case they jinxed it. They had problems in procurement, material tracking, progress tracking and reporting, billing — all of the things that one could presume Excel to handle just fine, but not at this scale. Implementing Fabtrol to manage estimating, drawings, materials and production was a big deal, since they needed new IT infrastructure, training, changed processes to be more modern— the speaker said it was “sheer terror”. Today, Fabtrol does estimating, procurement, material receiving and nesting, and they’re adding Bocad to streamline detailing. Lots of cost and time savings, lower waste on materials, and the security of a modern IT infrastructure. I hope AVEVA turns this into a case study, because the speaker highlighted truly business-changing effects of the implementation.
8. This theme, that AVEVA is more than 3D (MT3D) has been a cornerstone of AVEVA-speak for several years. The company really got its start with its PDMS CAD offering —always underpinned by its Dabacon database— but has struggled to make a name for itself outside that arena. For those not following so closely: Fabtrol for managing steel fabrication. Procon for contract management. ISM for standards management. ERM (Enterprise Resource Management) to track materials, labor and other project assets. AVEVA Net for information management — and to feed into AVEVA Engage for a visual front-end to Net’s data. I may have missed some products, but my point is: there’s much more then PDMS and E3D.
9. This plays out well in the Americas, where AVEVA’s business sounds fundamentally different from inother parts of the world. Americas EVP Amish Sabharwal told attendees that revenue in the Americas is growing at 25% per year (as opposed to 15% for the group overall); MT3D accounts for 50% of revenue (versus 25% overall) and that oil and gas represents 20% of the business in the Americas, compared to 50% for AVEVA as a whole. That’s a point to watch as the Schneider combination takes hold: how can the new AVEVA capitalize on what the Americas are doing to move beyond AVEVA’s traditional upstream oil and gas?
10. Finally, Southern Company’s job box is awesome. Mr. Weaver was speaking on stage, powerpointing away, and then walked down to the steel thing no one had really paid much attention to until that point. He opened the doors of the box, and we were all expecting a pile of paper drawings. Maybe a tablet. Nope. A huge, gorgeous display stole the scene. It was a great reveal, but with a serious purpose: doing what you’ve always done, in ways that are comfortable and familiar, won’t work much longer. Will digital technology replace all paper, everywhere? No. But the digital job box Southern Company showed us enables a lot of new ways to interact with design intent–and that can only lead to better outcomes, on this case, on the construction site.

Digitalization is a huge topic. It means many things, as each implementing company takes stock of its current situation and figures out its strategic directions. Do we want to bid more quickly and reliably on projects? Steal Aker’s templates idea. Digital job box? Manage CAD models and associated data with a view to making them available at the construction site (or plant operating floor). Giant spreadsheets too risky in your steel fabrication shop? Fabtrol. It’s a change in mindset that requires thinking beyond the immediate task to the downstream uses of the data being created, and being willing to take extra time to add in what those processes might require. The AVEVA user crowd at the event was at many different points in that thought process, but events like this move the needle forward every time.

Note: AVEVA graciously covered some of the expenses associated with my participation in the event but did not in any way influence the content of this post. The cover picture is of Southern Company’s job box — it’s not great, too backlit, but the best my iPhone could do. If I get something better, I’ll update.

► Quickie: Altair nabs ElectroFlo CFD for electronics cooling
21 Feb, 2018

Altair just announced that it has acquired TES International’s technology and intellectual property and hired founder Ben Zandi to lead its thermal solutions software development efforts. Dr. Zandi founded TES to address electronics cooling and today (yesterday?) the company provides solutions for thermal design and packaging, custom programming, general heat transfer, stress and vibration analysis, and CFD. TES’ main CFD product, ElectroFlo, is an electronics cooling package designed for high power-density applications. According to Altair, ElectroFlo uses coupled thermal/electrical algorithms, improving results accuracy for systems containing wires and traces and can be used to simulate everything from electrical components and printed circuit boards to full systems.

Dr. Zandi is quoted in Altair’s press release as saying that ElectroFlo will be combined with AcuSolve to “provide thermal solutions for applications with complex flow interactions, while coupling with Altair’s Electromagnetic Compatibility (EMC) and Electronic Design Automation (EDA) technologies will provide users a broad set of solutions for electronic applications.”

No financial details were announced but since Altair is now publicly traded, we’ll see if their coming Q4 2017 results offers more information.

► 10 things I think I think: SOLIDWORKS World 2018
12 Feb, 2018
SOLIDWORKS World is always a spectacle of maker-ness, designers competing to out-SOLIDWORKS one another in design competitions and learn from one another. It’s, as one speaker put it, nerd-heaven. This year was the twentieth anniversary event and many attendees proudly displayed buttons from past events. It’s hard to capture in a blog post but here are ten things I thought about as I talked to attendees, SOLIDWORKS and Dassault Systemes (DS) people and their partners:
1. I never did find out how many people were at this year’s event (5,000? 6,000?) but everyone I spoke with had a specific goal for attending: functionality to uncover, product strategy to learn, business to conduct. But without question, the main and common reason was community. A lot of attendees work in small shops where they’re the only SOLIDWORKS user; meeting others like them is a big deal, a chance to unwind, compare notes and connect. it’s also a chance to network for that next job, which brings up
2. Certification is a big deal. Quite a few of the attendees I spoke with were there to take a certification exam (for the first time, or to be part of the 20th anniversary of the certification program). It’s a big deal — nervous-making until it’s over, then a little happy-dance while the SOLIDWORKS crew takes the picture and hands over the certificate and swag bag. Without exception, the exam-takers see it creating legitimacy at their current employers and positioning for the future.
3. The flip side of these conversations: why aren’t more of you using simulation? It’s available in many of the SOLIDWORKS packages you already have! This CAE sessions I attended had 20-30 people, so there are some simulation users, but very few of the casual conversations turned up CAE as part of the typical design process. People over-design, think they don’t have the hardware, feel they don’t know enough to credibly explain the results … Lots of reasons but, honestly, none that really stand up today. It mostly comes down to already having too much to do, and a belief that simulation is for other people.
4. But the SOLIDWORKS team keeps trying: SIMULIA Structural Simulation Engineer (which I had been referring to as SIMULIA SimDesigner) is for the top end of that crowd and, while not yet generally available, demos well. SOLIDWORKS Simulation can do many things today, but not complex non-linear cases. Enter SIMULIA Structural Simulation Engineer, which aims to connect SOLIDWORKS and Abaqus NonLinear. It’s currently in Lighthouse (ie Beta) mode, but the demo I saw begins to address some of the differences between SOLIDWORKS’ way of doing things like connections and Abaqus’ — it’s a work in progress rig now but with a lot of promise.
5. xDESIGN, SOLIDWORK’s entry into browser CAD, also demos well (and CEO Gian Paolo Bassi showcased a number of user projects) but I didn’t talk to any current SOLIDWORKS users who were thinking of switching, even if they were interested in trying out xDESIGN. In part, people aren’t convinced that they’ll always have suitable WiFi, even in their offices, and are concerned about lost productivity. One important point: SOLIDWORKS staff typically talked about coming enhancements being in the desktop version and/or xDESIGN — it sounds like both versions will co-exist for the foreseeable future.
6. xDESIGN, the MySOLIDWORKS community, the cloud-compute component of SimDesigner and many other products discussed at SWW18 run on the 3DEXPERIENCE platform, parent company Dassault Systemes’ way to connect applications, users, data and external resources. The SimDesigner demo highlighted both the good and bad of the platform: collaborating around simulation results was easy, fast and intuitive —when it worked. WiFi died during the demo and so did the collaboration session. Not DS’ fault at all, but a reality of expecting to be connected at all times. There’s also still the problem that products on the 3DEXPERIENCE platform use the CGM CAD kernel while SOLIDWORKS uses Parasolid. Bridging the two requires work, a hard sell for long-time SOLIDWORKS users with a legacy of parts and assemblies
7. The Marketplace is another 3DEXPERIENCE offering that I think can, in time grow to serious significance. It aims to connect modelers to suppliers. Right now, 3D printing bureaus and some types of parts suppliers can offer their goods and services to SOLIDWORKS and CATIA users via in-CAD add-ons. Designers can compare prices, schedules and service options. I’ve asked DS for more details on this and will report back once my questions are answered.
8. Speaking of, 3D printing was huge at SOLIDWORKS World. Lots of vendors of both hardware and materials, cool debuts of more affordable production printers, in-CAD model checking and design assistance fueled many conversations. In a session on new technologies, the speaker asked for a show of hands of who was interested in 3D printing; just about everyone raised their hands (as opposed to a tiny handful for simulation, sigh.) I spent time with several printer makers and have to say: we’re getting to the point where part orientation, segmentation, supports and other print-specific factors are becoming less relevant. I hope to write in more detail about one supplier, Raze, sometime soon. Cool stuff there.
9. IoT was represented at SOLIDWORKS World, but not as heavily as I had thought it would be. Perhaps this is an audience of doers rather than new-business-opportunity-seekers, but the concepts of connectedness leading to preventative maintenance still seemed somewhat new. Surprising.
10. Also surprising was the PLM-ness of the event. DS used to keep separate the PDM-ness of the SOLIDWORKS message and the PLM-ness of its 3DEXPERIENCE/CATIA programs, but there’s more crossover than ever before. Yes, many SOLIDWORKS users use PDM-branded products yet their goals are very PLMish. SOLIDWORKS PLM Services and SOLIDWORKS Manage both start crossing the line into PLM. And that’s not  bad thing, since the benefits of PLM extend beyond CAD model/data management and are applicable to enterprises of all sizes.
11. (Yes, it’s 11. Still working on the format.) Finally, the users I spoke with are impressed by SOLIDWORKS 2018. Not everyone adopts every version and quite a few people have opted to stay on 2016 rather than move to 2017. But 2018 seems like it has enough in it to warrant the jump. And 2019  promises even more new stuff — it feels like the when to switch calculation is going to get more difficult as we learn more about the 2019 release.
Last thing: Special shoutout to the breakfast guys from Monday. We commiserated about the Patriots loss to the Eagles in a hard-fought Super Bowl and then got down to it: If you’re not a member of a user group, why not? SOLIDWORKS makes it as easy as possible to start or join a group and you get to influence SOLIDWORKS development — while networking with peers and eating pizza. Just GO!
Note: Dassault Systemes graciously covered some of the expenses associated with my participation in the event but did not in any way influence the content of this post.

► This time it’s Siemens, acquiring Sarokal for IC testing
7 Feb, 2018

The pace of acquisition really doesn’t jibe with the news that capital is getting harder to come by. Either that, or all of these companies have seriously deep pockets. Today. Siemens announced that it place to acquire Sarokal Test Systems to continue the buildout of its solutions for the electronics/integrated circuits/telecommunications world.

According to Siemens, Sarokal Test Systems makes “test solutions for fronthaul networks that are comprised of links between the centralized radio controllers and the radio heads (or masts) at the “edge” of a cellular network. Sarokal products are used by chipset vendors, fronthaul equipment manufacturers, and telecom operators to develop, test and verify their 4G and 5G network devices from the early design stages through implementation and field-testing … Sarokal’s tester product family addresses the entire development and maintenance flow for cellular and wired transmission system testing. The technology is especially designed to detect radio frequency (RF) problems. With Sarokal’s foresight into the requirements of 5G testing, their testing models were created from the beginning for both the virtual (digitalization) environment as well as the physical testing environment.” I have a tenuous understanding of what that means and will update once I am briefed and more knowledgable.

Harri Valasma, CEO of Sarokal, said in the announcement that “[b]ecoming part of Siemens and integrating our technology into [Mentor’s] Veloce emulation platform will give us greater visibility into early customer adoption of 5G, which can help us maintain our leadership as this segment is forecasted to grow rapidly.”

Terms of the transaction, which is expected to close before the end of March 2018, were not disclosed.

As I said, I understand the words but not the meaning. More soon.

Do you use Sarokai’s products? Why? What’s unique about them? Does it strike you as positive that they join the Siemens portfolio? Comment below or send me an email.

► Quickie: Aras acquires for PLM + MRO capabilities
6 Feb, 2018

Aras announced last week that it has acquired infoTRAK MRO from Infospectrum and renamed the product Aras Impresa MRO. MRO stands for Maintenance, Repair, and Overhaul and is a key component in many asset operators’ strategies: planning who, what, when and how to do maintenance to maximize uptime and profitability.

In making the announcement, Aras said, “With the Impresa acquisition, Aras will deliver PLM and MRO on a single, modern platform that extends the Digital Thread to the field and provides the foundation for Digital Twin.” The company said that its customers increasingly want to offer capacity-as-a-service, which means that they “need to transform how they develop products and plan to service them in the field. Connecting their PLM to MRO gives these companies a path to achieve both goals with a closed loop between product development and field data”. That’s absolutely key to many equipment makers’ thinking about reinventing their products in an IoT/Industry 4.0 age.

infoTRAK MRO managed everything from planning and scheduling maintenance events, to their execution with operational activities such as inspection and work card generation. From reading through the InfoTRAK MRO website, it seems targeted to the aerospace industry, but I would imagine that Aras will quickly make it more general-purpose.

No financial details were given, but Aras did say that it is acquiring technology, intellectual property, and subject matter expertise (ie. people). Aras plans to incorporate Impresa MRO onto the Aras PLM Platform. According to Aras, Impresa MRO will be available as part of Aras enterprise subscriptions and is immediately available at no charge for current Aras subscribers. So, go!
