An eta/DYNAFORM session begins with one of the following scenarios:

1.         The user provides CAD data (IGES, VDA, NX, CATIA or any other geometry data) that will be translated and read directly into eta/DYNAFORM database.

2.         The user provides FE model data (e.g. NASTRAN, LS-DYNA, etc.) that will be read directly into eta/DYNAFORM.

3.         CAD or FE model data is not provided.  The user begins with a blank database and generates or digitizes the line and surface data from a drawing.

Note: An example of a method of supplying or generating data is outlined in Sections 2.2-2.4.

Usually, a stamping simulation includes the following steps.
