PAM-CRASH 2G Interface

Engineering Solutions provides a complete pre-processing environment for preparing PAM-CRASH 2G data decks for analysis. Engineering Solutions can read existing PAM-CRASH 2G decks, create a model, display and edit PAM-CRASH 2G cards as they will look in the deck, and write a deck for analysis. Although Engineering Solutions also offers limited post-processing capabilities in results translation, you are encouraged to exclusively use HyperView. To create PAM-CRASH 2G decks in Engineering Solutions, you must load the PAM-CRASH 2G user profile with the appropriate template to access the full pre-processing capability.

Import and Export

PAM-CRASH 2G version VPS 2012 - 2019.
The PAM-CRASH 2G input translator also supports reading older PAM-CRASH 2G files 2002 - 2011 and map into the loaded template.
PAM-CRASH and PAM-CRASH 2G 2002 - 2011 templates are available in the installation and can be loaded. However they are no longer maintained.
During import all the GES associated with the solver keywords are mapped to entity sets in Engineering Solutions and associated with the solver entity. They are exported back as GES during export.
In addition to the custom export options available in the Export Browser, several templates are available to export specific solver entities only.

Mass Calculations

The mass of each element is calculated by density * volume. Density is retrieved from the material associated with the element’s component. Several assumptions are made in mass calculation based on PAM-CRASH 2G solver.
For rigid bodies (RBODY) of type 3 with a user-imposed center of gravity and mass and inertia properties, the structural mass of the PART components are replaced by the rigid body mass. All other keywords besides the PART keyword are neglected in the RBODY type 3 mass calculation.
The following table summarizes how each supported element in the Engineering Solutions PAM-CRASH 2G interface, except shells and solids, performs these calculations:
