Model Checking by Radioss Starter

Radioss Starter checks for consistency between format lines and prompts errors and warnings, if they exist. The output file runname_0000.out contains useful information helping to debug models.

The following checks are useful in the output file:

Errors and Warnings Messages

All errors must be corrected

Warning to be corrected:

Degenerated elements
Initial penetrations
Real incompatible kinematic conditions

Check Time Step (element and nodal)

How many elements control time step? If a few, then modify the mesh to optimize the time step.

Check Mass and Inertias

Mass scaling causes instability. It is worthwhile to check the center of gravity computed by Radioss. That should fit the physical center of gravity.

Note: Small elements, beams, springs and spot welds need to be closely observed.
