Splitting a Model in CFD-VisCART

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 FAST formats can be imported into CFD-VisCART.

Using the Delete Tool in CFD-VisCART V2007

CFD-VisCART has several tools to modify/delete model entities. Very often it is useful to erase unnecessary entities or clean up dirty geometry in order to simplify it. There are three available ways to delete entities in CFD-Viscart.

Visual Display of Bad Cells in CFD-VisCART

Most models have certain parts or regions where the grid density needs to be higher than other areas to accommodate for steep curvatures, sharply changing topology, etc.

Making it Easy to Add a Box Source in CFD-VisCART

Sources are used in CFD-VisCART to refine the grid in localized regions of the domain. One of the many types of sources available is the Box Source where the user specifies a cuboidal box around the region a finer grid is required. In the earlier versions, the user would have to add a Box Source and then specify its X, Y and Z extents to position the box in the desired location.

Saving Mesh Parameters in CFD-VisCART V2007

In CFD-VisCART V2007, the "Generate Mesh" panel was improved. Now, with the same icon, you can access all the different mesh types: Shrink Wrap, Stair Step, Projected Single Domain, and Multi Domain Meshes.
