      Hello community, I hope you are all doing well. My problem is that I'm trying to design a CFM resembling a gripper in static structural using TPU95A as the material. So far, I've tried activating large deflection, setting initial and minimum substeps to 100, and maximum substeps to 1000. I used Keyopt(6)==1 and Keyopt(2)==1. Additionally, I sized my mesh to 1.6mm, which I think is decent. I tried all these things because TPU95A is an elastomer; nevertheless, deformation results are still linear instead of nonlinear. What can I try now? Has anyone designed a CFM in ANSYS before?

      PD: Sorry for my bad english.
