Tips & Tricks

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.

CFD-VIEW: Working with cell-center data in batch mode

Many improvements have been made in CFD-VIEW that allows the manipulation of cell-center data. The latest cell-center data additions implemented in CFD-VIEW V2011.0 include, for example, support for the MinMax Probe and the Calculator.

"Per Pixel Lighting" display option in CFD-VIEW

When visualizing CFD solutions, it is often of interest to see a particular range of variable values, and it is therefore useful to be able to clip the surface coloring to that range, as to obtain a clearer view of the areas affected by the variable.

Visualizing decomposed model without zonal interface outlines

Running a simulation in parallel allows quicker turn around for larger and complex problems. Such parallel jobs require the computational domain to be decomposed into multiple zones. Such a multiple-zone file may be inconvenient to post-process in CFD-VIEW because zonal interface outlines will be visible and the original surfaces would have been split. As depicted in figure 1 below, these outlines can be numerous and may therefore hinder the clarity of the model.

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.).
