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.
