An eta/DYNAFORM session begins with one of the following scenarios:
1. The user supplies CAD-IGES or VDA or any other geometry data that will be translated and read directly into eta/DYNAFORM.
2. The user supplies model data (e.g. NASTRAN, LS-DYNA, etc.) that will be read directly into eta/DYNAFORM.
3. CAD or model data is not supplied. Therefore, the user begins with an empty database and generates or digitizes the line data from a drawing.
NOTE: An example of a method of supplying or generating data is outlined in sections 2.2~2.4.
A normal simulation includes the following steps.
