How to create a complex blank holder with PAM-DIEMAKER for CATIA V5

This video shows how the complex blank holder of a double action draw die can be created from multiple segments using a combination of standard CATIA and special PAM-DIEMAKER for CATIA V5 functions all available inside the Blank Holder dialog.

Improve trimming with Overshoot

Trimming in PAM-STAMP can fail due to a too short trimming segment curve leading to not cut properly the blank mesh. This can be solved by using Overshoot option in PAM-DIEMAKER for CATIA V5.

Using Region sources in CFD-VisCART

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 years back. To extend this tool set further, CFD-VisCART V2013.0 introduced Region sources.

Automatic covering of larger unwanted holes in CFD-VisCART

CFD-VisCART meshing automatically closes or covers holes in the geometry that are smaller in size than the cell size specified at the surfaces. To cover LARGER holes, the ‘Max Hole Size to Cover’ feature can be used. This feature, introduced in V2013.2, works to automatically cover larger holes in the geometry during mesh generation, and thus prevents the mesh from leaking into unwanted regions. This feature is available with all mesh types supported in CFD-VisCART.

Grouping parts during data import in CFD-VisCART

When dealing with complex industrial models such as cars and airplanes, hundreds of parts need to be managed. Each one of these parts may also be subdivided into different components. In order to easily manipulate these different parts and components in CFD-VisCART, you can make use of the grouping feature.
