From LS-Dyna to Radioss Problems encountered The definition of the MAT_RIGID in LS -Dyna is very simple and easy. In Radioss it is needed to define a complex equation. Once you get used it is ok. The MAT_DAMPER is very intuitive in LS -Dyna. In Radioss I found it translating a LS -Dyna damper with Hypercrash. Also a minor issue.
