Dear Miguel,Thank you for your reply. I also have contacts in the model and it stops after the contact has been initiated.how did you solve your contact problem?On Sun, Mar 28, 2021 at 3:12 AM Miguel Suarez <masuar...@gmail.com> wrote:I’ve had something similar in the past. I had a problem with a corner contact that would stop my simulation. There should be message files that you can open and search for error. I ran my analysis on 192 cores, so scanning those message files can be tedious. Also, scan your results to see if you notice any contact issues.Another issue that I found stopped my simulations is bolt preload. Do you have anything like that?

“SI 201” stands for Sliding Interface 201
This small contact penetration is not the problem.
Rather, something is causing elements to deform to the extent that the element’s Jacobian is negative. Have a look at the element numbers listed and try to determine what is causing their distortion.
