Wall

Purpose:

This interface is used for showing, creating, modifying, and deleting *RIGIDWALL cards in LS-DYNA. The main advantage of this interface is the ability to graphically view the various rigidwall definitions with the flexibility of positioning them using translate, rotate, and reflect functions.
