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 spotwelds need to be closely observed.
