► Feeds Sections Open Again
  29 Jan, 2017
Our aggregated RSS/Atom based CFD feeds are now working again. You can find them here:

https://www.cfd-online.com/Feeds/

Following these feeds is the quickest way to catch-up on the most recent CFD blogs, news, jobs, vendors and journals.

Here are direct links to the different Feed sections:
These feeds have been off-line for almost a month. The feeds were originally based on the Google Feed API service, which was discontinued by Google on Dec 31, 2016. We have now implemented our own RSS aggregator and cache system and we are now not dependent on any external service. Some of the original sources are not working with our new system though, and they have been removed. We are not sure why some of them are not working as before.

If you have any suggestion on other RSS sources to add to these feeds please let us know by responding to this post or sending an email to webmaster@cfd-online.com.
► Feeds section down
  12 Jan, 2017
Our Feeds services are currently off-line. This section was based on the Google Feeds API, a service that was discontinued and disabled by Google on Dec 15, 2016. We are investigating other ways to generate the Feeds.
► CFD Online Traffic Statistics for 2016 Finished, Fantastic Growth!
    6 Jan, 2017
We have just finished the traffic statistics for 2016 for CFD Online. The About section has been updated to reflect the developments in 2016.

2016 was a very successful year for CFD Online. We had a fantastic growth in traffic and for the first year ever CFD Online on average delivered more than 2.5 million web-pages per month to our visitors! Both the number of read web pages and the number of unique visitors (IP addresses) reached new record levels. The number of read web-pages increased by 39% and the number of unique visitors increased by 13% compared to the previous year. This is the strongest growth in traffic that we have ever had.


The bar chart above shows the 12-month trailing average of the number of web pages delivered from CFD Online per month over the last 18 years. More details about the traffic can be found in the most recent web-server statistics or in the statistics for 2016.
► Updated Android and iPhone/iPad Forum Apps
  12 Dec, 2016
We have just released new versions of the forum apps for Android and iPhone / iPad / iOS.

It is necessary to update to these new versions since we have now we switched to encrypted SSL/https based communication. These apps have several new features, an improved GUI and many bug-fixes.

The apps are free and can be found here:

Android: https://play.google.com/store/apps/d...nlinecomForums

iPhone/iPad/iOS: https://itunes.apple.com/us/app/cfd-...936248777?mt=8

Use these apps to follow the forums also when you are on the move.
► CFD Online Adds SSL Encryption
    5 Dec, 2016
Today we have switched over the entire www.cfd-online.com site to encrypted SSL using the https protocol. All old pages starting with http:// should now automatically be forwarded to an encrypted https:// address instead.

This increases security and makes it impossible for people to eavesdrop on your communication with cfd-online.com.

I hope that we have managed to change everything on our site from http: to https:. If you notice anything broken please let me know.
► Problem to Post New Threads in Forums Solved
  13 Nov, 2016
Since late Friday it has not been possible for normal users to post new threads on the forums. For some reason it worked well for moderators, so we didn't notice this problem until we started getting emails about it.

The problem has now been solved and I hope that it should now work well for all registered users to post new threads. It was an unused forum plugin that for some reason after a software update started to give server errors.

Looking forward to seeing you in Duisburg!
► OpenFOAM User Training in Ottawa, Canada Feb 21-22 offered by Applied CCM
  16 Jan, 2017
This is a 2 day OpenFOAM® training designed to enable CFD users to start using OpenFOAM for practical computations. The course consists of a series of lectures that provide a general understanding of OpenFOAM topics followed by hands-on work. Along with the hands-on examples that show “how”, the lectures include discussion of “why”. The goal of this approach is to enable participants to independently use OpenFOAM in their daily work. No knowledge of the OpenFOAM library is assumed. Basic Linux commands and their relationship to hands-on examples are covered.

We will be hosting it at the University of Ottawa, in the heart of Ottawa within a few blocks of Parliament Hill, the Byward Market and the world famous Rideau Canal. If you need accommodation or travel suggestions send me a note. You can register on-line here, on our website, or contact me directly to reserve your spot. There is limited seating so I encourage you to register early.

The full event description is attached. Contact me for any additional details or questions.

-Chris

► New CastNet Release: GUI Environment for OpenFOAM and CalculiX
  13 Jan, 2017
New CastNet Release: GUI Environment for OpenFOAM and CalculiX

CastNet V5 for OpenFOAM® and CalculiX

DHCAE Tools GmbH is proud to present a new release of the modelling and simulation environment CastNet.

CastNet is a pre-processing tool that supports the complete workflow of CFD applications: CAD import, mesh generation and case setup, runtime control and monitoring of the simulation job and, finally, post-processing.

CAD import: CastNet is capable to work with geometric modelling kernel input files directly (Parasolid, ACIS, Granite). This way, all customary CAD systems are supported.

Supported open source solver technology: CastNet facilitates a convenient and professional usage of open source solver technology in an industrial environment.

CastNet provides a comprehensive support for the OpenFOAM® releases, starting with 2.1, up to
  • OpenFOAM-Foundation Release 4.0/4.1 and
  • ESI-OpenCFD Release v1606+.

For Windows users the OpenFOAM® ports blueCFD-Core-2.3 and blueCFD-Core-2016 from blueCAPE are supported.

For Structural Analysis the FEA solver CalculiX is supported by CastNet. CalculiX is a finite element solver for stress analysis with non-linear capabilities such as contact or non-linear material behaviour.



Meshing technology: CastNet provides a reliable and stable CFD/FEA meshing technology including boundary layer meshing, mesh extrusion capabilities and hex-core meshing. Furthermore, OpenFOAM®'s snappyHexMesh is supported to work with the CAD model entities (regions, surfaces, edges) directly.

HPC Cloud Resources: DHCAE allows using HPC cloud resources directly from the GUIs, for example 4 instances Amazon-c4.8xlarge with a total of 72 physical cores. The CloudSME platform guarantees a transparent cost management and high usability.

Extended snappyHexMesh support: In the new CastNet release the support of Conjugate Heat Transfer (CHT) solvers has been extended to snappyHexMesh. An arbitrary number of regions can be set up for CHT cases.

Extended fvOption support: CAD regions can now be defined as cellZones with additional source terms during runtime, for example heat sources for the heat equation etc.

Extended boundary condition support: More boundary conditions are supported directly, for example variableHeightFlowRate for VOF applications or individual wall interaction for Lagrangian particle solvers.

Templated case setup: CastNet provides an efficient template system to speed up the case definition significantly. Predefined optimized solver settings and mesh parameters can be applied directly, thus reducing time-consuming and error-prone manual definitions.

FSI support: DHCAE provides extensions for FSI simulations with OpenFOAM coupled with CalculiX.



Key features of OpenFOAM® support: CastNet supports more than 30 OpenFOAM® solvers and numerous OpenFOAM® utilities. In particular, a direct setup for the conjugate heat transfer solvers is available. Arbitrary Mesh Interface (AMI) applications can be defined within the GUI as well. Cell zone and face zone based features (porous zones, baffles, fans etc.) can be defined on the CAD model entities directly.

Cross platform support: CastNet can be run on both Windows and Linux. Simulation cases can be exchanged between the different operating systems. This way the user can stay within his Windows environment for CAD applications, mesh generation and case setup while running the simulations on a high performance Linux cluster.

Runtime job control: With the runGui tool, a suitable and powerful job control system is provided. Amongst others, convergence monitoring, access to OpenFOAM® utilities, automatic solver stabilization during runtime and direct access to HPC Cloud Resources is available within a single graphical user interface.

Video tutorials: Our video tutorials allow you to quickly familiarize yourself with CastNet. Some demonstration videos are provided on our web page.

This offering is not approved or endorsed by OpenCFD Limited, producer and distributor of the OpenFOAM software and owner of the OPENFOAM® and OpenCFD® trade marks.
