Inverting Models in CFD-CADalyzer |
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.

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. Levels
in CFD-GEOM are used as a visual grouping tool, allowing you to
Show/Hide certain parts of your model easily and quickly

Grouping of Geometry Surfaces in CFD-VisCART V2008.0 |
|
In CFD-VisCART V2008.0, a new Group/Ungroup capability has been added for geometry surfaces. Grouping is
useful for collecting multiple geometries having the same meshing parameters and/or boundary conditions.

Usually, when performing a particular simulation, it is necessary to compare the results of
similar models or the same model at different operating conditions. It is
important that the two (or more) cases being compared be viewed from the same
angle and at the same zoom level.

Importing Native CAD Files into CFD-GEOM V2008.0 |
In CFD-GEOM V2008.0, new CAD import options have been added to support
native CAD file import into CFD-GEOM. With these new import options,
you no longer have to translate the file to SAT or IGES format.

Hybrid Meshing in CFD-GEOM V2008.0 |
|
Hybrid meshes can help in
optimizing grids in complex geometries allowing for structured meshes
in one part of a geometry, while using unstructured grids in more
complex regions. This
tip will show you how to create a simple hybrid (structured/tetrahedral) mesh
system in CFD-GEOM V2008.0, as shown in Figure 1.
