Tips & Tricks

Make an independent setup from existing pre and rst files in PAM-STAMP

Sometimes only rst files there are available and dependent pre file of an intermediate stage setup (lost data, picking with a process variant, …), which is not possible to run in another PAM-STAMP version, usually in newer version. It is possible to create a pre file independent on preceding rst files.

Determination of Krupkowsky parameters for hardening curve

In case there are no measured material data for simulation purposes, it is possible to determine hardening curve from information usually provided by material supplier.

How to import a PAM-STAMP result into CATIA V5 with VRML export format ?

For a comparison of the virtual stamped part and the nominal CATIA V5 part one can use PAM-STAMP, or go back to CATIA. Since the meshed part is not easily converted into surfaces again, one solution is to use an overlay of the CAD part and of a VRML export of the stamp part.

How to encrypt material data sets in PAM-STAMP?

Major automotive companies spend a lot of money to describe all materials used in their simulation processes. To ensure simulation quality also at supplier sites, they want to give the material data sets to them, but not for free. One half of the solution is material encryption, the other a predefined expiration date.

Small collection of 3D meshed symbols for illustration purposes

During a project the need to visualize the functionality in 3D arose and some 3D symbols were created, which are now made available as a goody.

How to find out what forces are working inside the sheet or tube section ?

If you need insight on the restraining force of a geometrical drawbead or want to know the transmitted force in a sheet or tube section, you can define a force gauge.

Part to part positioning based on mesh geometry

Sometimes the car coordinate system is not available with the stamped part. So if one wants to map stamp results, to an assembly operation, first of all the part needs to be transformed to the right position.

Using the BC/VC Queries tool in CFD-GEOM

Have you ever whished that you could blank/unblank or pick/unpick only interfaces in a CFD-GEOM model? You can now with the BC/VC Queries tool. This tool allows you to pick, unpick, blank or unblank all the interfaces of the current model based on the interface type (Fluid/Fluid, Fluid/Solid, etc.).

How to create Pyramid cells on structured-unstructured domain interfaces in CFD-GEOM

CFD-GEOM can be used to construct a variety of cell shapes: quadrilaterals (2D) and hexahedrals (3D) for structured meshes; triangles (2D) as well as tetrahedrals and polyhedral/honeycomb (3D) for unstructured meshes; prisms and pyramids (3D) for semi-structured meshes.

New Exposed Boundaries Visualization tool in CFD-GEOM

One of the various new features introduced in CFD-GEOM V2009.2 is the ‘Exposed Boundaries’ visualization tool. This tool allows users to quickly visualize those areas where closure problems remain in an otherwise closed and “watertight” model.
