Hello,

I am trying to simulate geometry behavior of rubber like material under compression in a 2d nonlinear analysis. I am getting an error that the solver has numerical difficulties (see first appendix). If I suppress the contact sets it will solve completely however the part will interfere with itself. So my assumption is that it has to do with the large deformations in combination with a lot of surface contact. Does anyone have an idea to solve this issue?

Thanks,

Raoul

Hi Raoul,

I haven't had any joy getting it to run to completion without overlapping on contact areas, even with a very small time step it seems to struggle.

We are probably reaching the limit of what can be achieved in SW.

Cheers
