Thank you for your reply and sorry for the long time for answering.nnI've been doing some smaller models to understand better the non convergence. I did a very simple model with thick bodies. Soft material is compressed by two bodies made of steel. As you said, with the hyperelastic material it converges. Instead, when I try to compress a polyethylene body elements get highly distorted. nMooney-Rivlin result (converged):n
PE result (unconverged):n
Second try PE result (unconverged, stopped at 82%):n
The reason according to solver output is element violations. Newton-raphson residuals and element violations are as follow:n
Would you have any suggestion on how to handle high deformation of linear materials with a high poissons value in Ansys mechanical, whether it's possible?.Thanks again,nMonin
