Hi,
I am trying to model a compression test for aluminium. In my model I have a 2D rigid plate and a 2D deformable part. And also my part have some space in itself. I used dynamic explicit step with 0.01 time period. It also run somewhere. But then exited with an error. It has some convergence diffuculties. I also tried to adaptive mesh but it gave me same error early. Also I can see the result of solved part and I looked reaction force. I saw too much oscilation for force-time graph. Can anyone help me to solve this problem. I also attached the inp file of model.
