Divergence in Implicit Simulation Hyperelastic Material

Hello Community,

 

how can I prevent my implicit simulation to diverge (see attached figures of the engine OUT file)?

 

There is a sentence in the RADIOSS v13 User Guide: 'For the hyper-elastic type laws (42, 62, 69, and 82), special treatments have been done to avoid the divergence.' 

 

I have a problem similar to “Example 42: Rubber Ring” with my own model (also hyper-elastic material - MAT42).

 

The settings in the engine file for my model are almost the same to Ex.: 42.

    I hope you would have solved this query with Radioss Explicit.
