The model building refers to a loadcase (example: front crash on rigid wall at 35 mph.). The loadcase file location is set in a main table file, $MCRASHDIR/modmng/loadcase_main.tbl.

Loadcase file description

The loadcase file may be defined where the user wants because the full path is defined in the loadcase main table. The default setting is located in the directory, $MCRASHDIR/loadcase/.

Card 1:

This card defines the keyword that will be displayed on the Model Manager sub-model list.

/MODMNG/LOADCASE/SCREEN_KEYWORD

keyword_group_name_1

keyword_group_name_2

…

String

No

Card 2: sub-model definition

This card defines a sub-model (or component) described with keywords that will be loaded to create the complete model according to the loadcase.

If the vector direction is also defined in the submodel (B00 file), HyperCrash will rotate the submodel until both directions are the same. The rotations are done around the point (0,0,0).

If the Angle value is different from 0, HyperCrash will rotate the model around the vector direction and around the point (0,0,0).
