There is a growing demand and challenge in different industries, especially semiconductor and MEMS areas, to have increased wafer size with reduced feature size, i.e. high quality process uniformity.
For better visualization of the geometry and mesh, a model clipping feature was introduced in CFD-VisCART and CFD-GEOM V2013.0. The following sections illustrate the usage and benefits of this feature.
In certain applications, different regions of the computational domain experiences flow conditions that are so different that it is very difficult for a single solver to produce accurate results at the extremes. In many situations, such problems can be...
Handling large models in CFD-GEOM is quite easy, but often there are thousands of entities, making it hard to sort out particular entities among them all. For cases like these, a visual grouping mechanism in CFD-GEOM makes viewing such models very efficient....
Sometimes during the creation of a geometric model it is possible to have overlapping (duplicate) points, line, edges, and faces. This can also occur when CAD files are imported into CFD-GEOM. The user usually finds this situation when trying to do additional...
In some cases, you might have to perform the same task several times to post-process your results in CFD-VIEW. This can happen for example when you are running a parametric study and need to extract the same information from all the solution files. In this...
This course introduces users to the Visual-Environment for OpenFOAM. It provides users with a GUI-based workflow for preparing, solving and post-processing OpenFOAM cases:
- Seamless import from most CAD formats
- Easy clean-up of CAD...
CFD-VisCART allows you to handle extremely complex geometries with lots of details. Often, you may have a geometry that you only modify slightly, but would like to use the mesh parameters that you used previously. In order to make this very simple, a batch...
CFD-GEOM has many tools that can make viewing and manipulating your models easier. When you create your model, CFD-GEOM will show the handles for entities that are created. These handles are more like a wire frame representation of the model.
CFD-VisCART is a 3D unstructured adaptive Cartesian mesh generator. It is ideally suited for external aerodynamics and automotive underhood applications involving extremely complex geometries. Models/geometries in SAT, Parasolid, STL, Nastran, 3DS, Plot3d and...
The Plotter operator in CFD-VIEW supports signal processing for Time History data. A previous user tip – Digital Signal Processing using CFD-VIEW – shows how time history date can be made available and how to perform a PSD on a periodic...
In order to control grid spacing at user-defined locations, mesh sources are a common tool in CFD-VisCART (Figure 1). Point, Line, Curve, Plane, Box and Surface sources have been available for several years. Cylinder and Sphere sources were introduced a few...
Computational Fluid Dynamics (CFD) requires the discretization of a geometry bounded by it's wetted surfaces. In CAD, the solid parts are created without the corresponding fluid volumes, i.e. negative space.
When handling complex geometries in CFD-VisCART, the list of geometric surface can quickly become very large and make the management of the model rather tricky.
By using the Group feature in CFD-VIEW, you can easily manipulate multiple objects.Oneof the advantages for large models is it will decrease the size of the object list.
In most CFD simulations, it is required to place inlets/outlets far enough from the region of interest in order to reduce their influence on the solution. In many applications, this can be done by extruding existing inlets/outlets BC patches away from the...
When post processing a simulation in CFD-VIEW, you will often be working with multiple types of objects. Volumes and Surfaces are two types objects that you will most definitely have whether the model is 2D or 3D.
In CFD-VisCART, the 'Fit to View' function was improved in V2007. It now checks the blanking status before setting the view. In this tip, a car model will be used to demonstrate the Fit to View capability.
In CFD-GEOM, certain entities can now be set to transparent. This option allows you to add transparency effects to your surfaces, faces, and volumes. This can be an excellent way to add shadows/colors and glass effects to the model.
