<div>NOGRID provides flow simulation solutions for you with the software products <br />
NOGRID points (commercial meshless CFD code) and <br />
Nogrid pointsBlow (commercial meshless CFD code)<br />
<br />
Current version of Nogrid ''points'' is 6.1.7 (at January 2017). <br />
<br />
Current version of Nogrid ''pointsBlow'' is 2.7.4 (at January 2017)<br />
<br />
'''NOGRID points''' software, based on the Finite Pointset Method (FPM), is a Computational Fluid Dynamics (CFD) software package for simulation tasks in a wide area of flow and continuum mechanical problems. FPM is a method for the solution of the equations governing viscous fluid flows, including the effects of heat and mass transfer. NOGRID points software models problems in continuum mechanics. The method solves not only fluid flows, but also problems with elastic or plastic deformations. More generally spoken, NOGRID points software considers all the viscous as well as elastic/plastic stress tensors and any mixture of it.<br />
<br />
NOGRID points software is based on FPM as a grid-free method which, in contrast to classical numerical methods, such as Finite Elements or Finite Volumes, it does not require a grid or mesh. NOGRIDs flow simulation software is one of the latest technologies in the area of numerical flow simulation. Classical numerical methods (such as Finite Elements or Finite Volumes) need a grid or mesh for simulation. The generation of mesh takes a long time. Our NOGRID points-CFD (Computational Fluid Dynamics)-software is a grid-free (or meshless) method which, in contrast to classical numerical methods, such as Finite Elements or Finite Volumes, does not require a grid or mesh. The points are automatically filled, moved, refilled and cleaned depending on user specifications. The point cloud can be defined variously, e.g. constant in the whole flow domain, changing with time or increasing/decreasing locally depending on the flow/geometry situation. <br />
Nogrid points can be applied in the case of all problems, where grid-based methods reach their limits. Examples are fluid dynamical problems with free surfaces, moving parts, multiphase flows, fluid-structure interactions with a strong change of the computing domain or mechanical problems with substantial structure changes.<br />
<br />
<br />
Nogrid has developed a forming simulation software especially for the glass container industry. The name of the software is '''NOGRID ''pointsBlow''''' and the software computes the glass container forming process in full 3D. NOGRID ''pointsBlow'' software allows simulating all three kinds of container glass forming processes: BB (Blow and Blow), PB (Press and Blow or Wide Mouth PB) and NNPB (Narrow Neck Press and Blow).<br />

<div>== CFD in glass industry == <br />
<br />
CFD has a long tradition in glass industry. The measurement of flow quantities is very difficult and therefore simulation greatly helps to understand, evaluate and optimize all applicable processing steps.<br />
<br />
=== Process steps in the glass industry === <br />
<br />
Typical process steps in the glass industry are <br />
<br />
* melting<br />
* distribution<br />
* homogenization <br />
** stirring the glass in special homogenization systems<br />
* conditioning<br />
* hot forming<br />
** feeding, blowing, pressing, rolling, casting, drawing, floating, spinning, ...<br />
<br />
<br />
The hot end of a glassworks is where the molten glass is formed, beginning when the batch is fed at a slow controlled rate into the furnace. The furnaces are natural gas or fuel oil fired and operate at temperatures up to 1700°C. The temperature is limited by the quality of the furnace superstructure material and by the glass composition.The molten glass flows from a subducted channel known as the furnace throat into the refiner and forehearth channels. These channels transport the glass to the glass forming area. These channels cool the glass very precisely so that the glass at the forming area is of a uniform and exact temperature.<br />
<br />
==== Homogenization ====<br />
<br />
In glass industry, the function of stirring is to create uniform, homogeneous glass. Stirring equipment operates at high temperatures and under high mechanical stresses, so stirring devices have to be robust and often involve large amounts of platinum or platinum alloys. Although stirrers, stirrer bars, blenders, homogenizers, screw plungers and plunging stirrers currently used are generally effective in operation, reliable and with predictable lifetime, lower cost and improved operational efficiency are main targets for the future.<br />
<br />
==== Feeding ====<br />
Glass making processes from containers to tableware to TV glass begin with a droplet (gob) being delivered to the forming machines. In a large measure the success of the entire operation depends upon the uniform quality of the gob.<br />
<br />
==== Forming processes ====<br />
<br />
Depending on the final product a huge number of forming processes are known. For example for glass container currently two primary methods exist - the blow and blow method and the press and blow method. Various processes are available to produce thin flat glass sheets (Floating, Rolling, Overflow-Fusion, FOURCAULT drawing, ASAHI drawing, PITTSBURGH process, Down-Draw process). Depending on the product specifications each process has its pros and cons.<br />

<div>NOGRID provides flow simulation solutions for you with the software products <br />
NOGRID points (commercial meshless CFD code) and <br />
Nogrid pointsBlow (commercial meshless CFD code)<br />
<br />
Current version of Nogrid points is 4.2.2 (at June 1, 2012). <br />
<br />
Current version of Nogrid pointsBlow is 2.0.2 (at September 10, 2012)<br />
<br />
'''NOGRID points''' software, based on the Finite Pointset Method (FPM), is a Computational Fluid Dynamics (CFD) software package for simulation tasks in a wide area of flow and continuum mechanical problems. FPM is a method for the solution of the equations governing viscous fluid flows, including the effects of heat and mass transfer. NOGRID points software models problems in continuum mechanics. The method solves not only fluid flows, but also problems with elastic or plastic deformations. More generally spoken, NOGRID points software considers all the viscous as well as elastic/plastic stress tensors and any mixture of it.<br />
<br />
NOGRID points software is based on FPM as a grid-free method which, in contrast to classical numerical methods, such as Finite Elements or Finite Volumes, it does not require a grid or mesh. NOGRIDs flow simulation software is one of the latest technologies in the area of numerical flow simulation. Classical numerical methods (such as Finite Elements or Finite Volumes) need a grid or mesh for simulation. The generation of mesh takes a long time. Our NOGRID points-CFD (Computational Fluid Dynamics)-software is a grid-free (or meshless) method which, in contrast to classical numerical methods, such as Finite Elements or Finite Volumes, does not require a grid or mesh. The points are automatically filled, moved, refilled and cleaned depending on user specifications. The point cloud can be defined variously, e.g. constant in the whole flow domain, changing with time or increasing/decreasing locally depending on the flow/geometry situation. <br />
Nogrid points can be applied in the case of all problems, where grid-based methods reach their limits. Examples are fluid dynamical problems with free surfaces, moving parts, multiphase flows, fluid-structure interactions with a strong change of the computing domain or mechanical problems with substantial structure changes.<br />
<br />
<br />
Simulation, especially fluid flow simulation or CFD (Computational Fluid Dynamics) is not usually easy to operate and companies commonly need CFD experts to compute such tasks. To overcome this sticky situation, in the last two years Nogrid has developed a forming simulation software especially for the glass container industry. The name of the software is '''NOGRID pointsBlow''' and the software computes the glass container forming process in full 3D. NOGRID pointsBlow software allows simulating all three kinds of container glass forming processes: BB (Blow and Blow), PB (Press and Blow or Wide Mouth PB) and NNPB (Narrow Neck Press and Blow).<br />

Current version of Nogrid points is 4.2.2 (at June 1, 2012). <br />
Current version of Nogrid pointsBlow is 2.0.2 (at Sept 10, 2012)<br />
<br />
NOGRID provides flow simulation solutions for you with the software products Nogrid points and Nogrid pointsBlow. <br />
<br />
'''NOGRID points software''', based on the Finite Pointset Method (FPM), is a Computational Fluid Dynamics (CFD) software package for simulation tasks in a wide area of flow and continuum mechanical problems. FPM is a method for the solution of the equations governing viscous fluid flows, including the effects of heat and mass transfer. NOGRID points software models problems in continuum mechanics. The method solves not only fluid flows, but also problems with elastic or plastic deformations. More generally spoken, NOGRID points software considers all the viscous as well as elastic/plastic stress tensors and any mixture of it.<br />
<br />
NOGRID points software is based on FPM as a grid-free method which, in contrast to classical numerical methods, such as Finite Elements or Finite Volumes, it does not require a grid or mesh. NOGRIDs flow simulation software is one of the latest technologies in the area of numerical flow simulation. Classical numerical methods (such as Finite Elements or Finite Volumes) need a grid or mesh for simulation. The generation of mesh takes a long time. Our NOGRID points-CFD (Computational Fluid Dynamics)-software is a grid-free (or meshless) method which, in contrast to classical numerical methods, such as Finite Elements or Finite Volumes, does not require a grid or mesh. The points are automatically filled, moved, refilled and cleaned depending on user specifications. The point cloud can be defined variously, e.g. constant in the whole flow domain, changing with time or increasing/decreasing locally depending on the flow/geometry situation. <br />
<br />
<br />
Nogrid points can be applied in the case of all problems, where grid-based methods reach their limits. Examples are fluid dynamical problems with free surfaces, moving parts, multiphase flows, fluid-structure interactions with a strong change of the computing domain or mechanical problems with substantial structure changes.<br />
<br />
'''Nogrid pointsBlow'''<br />
Simulation, especially fluid flow simulation or CFD (Computational Fluid Dynamics) is not usually easy to operate and companies commonly need CFD experts to compute such tasks. To overcome this sticky situation, in the last two years Nogrid has developed a forming simulation software especially for the glass container industry. The name of the software is NOGRID pointsBlow and the software computes the glass container forming process in full 3D. NOGRID pointsBlow software allows simulating all three kinds of container glass forming processes: BB (Blow and Blow), PB (Press and Blow or Wide Mouth PB) and NNPB (Narrow Neck Press and Blow).<br />

<div>== CFD in glass industry == <br />
<br />
CFD has a long tradition in glass industry. The measurement of flow quantities is very difficult and therefore simulation greatly helps to understand, evaluate and optimize all applicable processing steps.<br />
<br />
=== Process steps in the glass industry === <br />
<br />
Typical process steps in the glass industry are <br />
<br />
* melting<br />
* distribution<br />
* homogenization <br />
** stirring the glass in special homogenization systems<br />
* conditioning<br />
* hot forming<br />
** feeding, blowing, pressing, rolling, casting, drawing, floating, spinning, ...<br />
<br />
<br />
The hot end of a glassworks is where the molten glass is formed, beginning when the batch is fed at a slow controlled rate into the furnace. The furnaces are natural gas or fuel oil fired and operate at temperatures up to 1700°C. The temperature is limited by the quality of the furnace superstructure material and by the glass composition.The molten glass flows from a subducted channel known as the furnace throat into the refiner and forehearth channels. These channels transport the glass to the glass forming area. These channels cool the glass very precisely so that the glass at the forming area is of a uniform and exact temperature.<br />
<br />
==== Homogenization ====<br />
<br />
In glass industry, the function of stirring is to create uniform, homogeneous glass. Stirring equipment operates at high temperatures and under high mechanical stresses, so stirring devices have to be robust and often involve large amounts of platinum or platinum alloys. Although stirrers, stirrer bars, blenders, homogenizers, screw plungers and plunging stirrers currently used are generally effective in operation, reliable and with predictable lifetime, lower cost and improved operational efficiency are main targets for the future.<br />
<br />
==== Feeding ====<br />
Glass making processes from containers to tableware to TV glass begin with a droplet (gob) being delivered to the forming machines. In a large measure the success of the entire operation depends upon the uniform quality of the gob.<br />
<br />
==== Forming processes ====<br />
<br />
Depending on the final product a huge number of forming processes are known. For example for glass container currently two primary methods exist - the blow and blow method and the press and blow method. Various processes are available to produce thin flat glass sheets (Floating, Rolling, Overflow-Fusion, FOURCAULT drawing, ASAHI drawing, PITTSBURGH process, Down-Draw process). Depending on the product specifications each process has its pros and cons.<br />

The hot end of a glassworks is where the molten glass is formed, beginning when the batch is fed at a slow controlled rate into the furnace. The furnaces are natural gas or fuel oil fired and operate at temperatures up to 1700°C. The temperature is limited by the quality of the furnace superstructure material and by the glass composition.The molten glass flows from a subducted channel known as the furnace throat into the refiner and forehearth channels. These channels transport the glass to the glass forming area. These channels cool the glass very precisely so that the glass at the forming area is of a uniform and exact temperature.<br />
<br />
==== Forming process ====<br />
<br />
Depending on the final product a huge number of forming processes are known. For example for glass container currently two primary methods exist - the blow and blow method and the press and blow method. Various processes are available to produce thin flat glass sheets (Floating, Rolling, Overflow-Fusion, FOURCAULT drawing, ASAHI drawing, PITTSBURGH process, Down-Draw process). Depending on the product specifications each process has its pros and cons.<br />

<div>Fluid-structure interaction (FSI) simulations are coupled CFD (fluids) and [[FEM]] (mechanics) cases. FSI is a part of [[mulitphysics simulations]] and an actual main focus in CFD development. As these solvers use different methods and codes, the transfer of the boundary conditions at the interface is an important feature of an FSI solution. <br />
<br />
== Coupling ==<br />
=== 1-way FSI ===<br />
1-way FSI typically describes the pure mapping of physical properties resulting from the analysis of a CFD-/FE-model to another FE-model. The two models typically do not rely on matching meshes (e.g. mapping aerodynamic pressure distribution onto a structural Finite Element model). However in the case of 1-way FSI the mapping of the physical properties does not include the modification of any of the meshes. <br />
<br />
=== 2-way FSI ===<br />
In the case of 2-way FSI the mapping is done in an iterative loop i.e. the results of the first model are mapped to the second model and these results are mapped back to the first model and so on until convergence is found or the process is stopped manually. Very often in the case of 2-way FSI one of the mapping steps involves the modification/morphing of the mesh of one or both of the models (e.g. mapping deformations coming from aerodynamic loads back to the CFD-model and re-evaluating the CFD-model in the deformed configuration).<br />
<br />
== Mesh Morphing ==<br />
In most cases FSI is quite simple to realize even employing meshes not matching. However as soon as mesh-morphing is needed the whole process gets much more difficult and only few software solutions are around that can handle this. They key-problems with mesh-morphing are:<br />
<br />
* Performance: Typical CFD-models as employed today in Formula 1 or Aerospace require very efficient morphing algorithms. A lot of the straight-forward approaches are not able to handle CFD-models consisting of several millions of cells.<br />
* Surface Quality: For calculating pressure distributions in aerodynamics the surface quality in terms of continuity has to be quite high. Otherwise one starts to observe oscillations in the pressure fields. This is namely a challenge in the case where the mesh providing the deformation (typically the structural FE-mesh) is significantly coarser then the surface mesh of the CFD-model (which is quite common).<br />
<br />
<br />

* Aero-elasticity<br />

<div>NOGRID FPM is a commercial CFD code. It is a product of NOGRID GmbH. <br />
<br />
Current version is 3.61 (at Okt. 1, 2008). <br />
<br />
Nogrid's Finite Pointset Method (FPM) is software for simulation tasks in a wide area of flow and continuum mechanical problems. FPM is a particle method, i. e. a grid-free method which, in contrast to classical numerical methods, such as Finite Elements or Finite Volumes, does not require a grid or mesh. <br />
<br />
FPM can excellently be applied in the case of all problems, where grid-based methods reach their limits due to the necessary remeshing. Examples are fluid dynamical problems with free surfaces, multiphase flows, fluid-structure interactions with a strong change of the computing domain, or structure mechanical problems with substantial structure changes.<br />
<br />
FPM is a most modern technology based on a particle method to solve the Navier-Stokes equations. Using the fast and robust FPM solver the usual long modelling and computing times can be shortened substantially.<br />
<br />
Increase your added value and secure your competitive advantage!<br />
<br />
* Extremely short modeling time<br />
* Dramatically reduced computing time<br />
* Easy data exchange to existing CFD/CAE environments<br />
* Direct import of models from CAD-Systems<br />

<br />
Why meshless modeling with Nogrids FPM?<br />
<br />
Our FPM (Finite Pointset Method) software is based on the so called particle method. Contrary to classical methods this method requires no mesh for the discretization of differential equations. FPM points are automatically filled, moved, refilled and cleaned depending on user specifications. The point cloud can be defined variously, e.g. constant in the whole flow domain, changing with time or increasing/decreasing locally depending on the flow/geometry situation.<br />
<br />
The main advantages of our FPM software are<br />
<br />
* Easy modeling of all free surface problems<br />
* Simple representation of multiphase flows within FPM<br />
* Natural interface for the description of moving parts and boundaries<br />
* Straightforward solutions for Fluid Structure Interaction (FSI) tasks<br />
* Very short computation time in comparison to classical methods without reducing results quality<br />
