Hello. I am using materials studio 2023 version. I set the maximum iteration to 20000 in the geometry optimization task of the Forcite module, but the iteration continues to end at 2000 units. I've tried over 30 times and it keeps happening. For convergence tolerance, only max energy and max stress were set to the minimum values. Is there any way to solve this? Information about the model is attached. Also under WARNING Convergence criteria are not satisfied. I wonder why such a phrase appears, but the convergence condition is not satisfied and the optimization task ends.

Thank you so much for your help
