Hello everybody,
I’m running a nonlinear-quasi-static analysis with OptiStruct and I have got some troubles with convergence.
What I exactly did is, running the same analysis for the same model but with different element sizes and when I mesh with very small size othewise by small size elements I get that problem with non convergence.
My model is built of 2 parts, the first one is fixed from one side and the other one presses the first part through radial and axial forces, between those parts I've built a contact. (see the following figure)
You find attached an Excel-file where some results are showed, so you can get a good idea about.
It would be kind of you if you could help me to solve this problem.
Thank you in advance
Best Regards
M. Lamzoughi
