Nonlinear Analysis with large displacement and contact

Question asked by Raoul Jansen on Jul 17, 2015

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
