I am now using 2023 R2. After updating my software I tried to run an earlier archive which I have been using as a baseline with no convergence issues for my previous version. I have not been successful in making my model converge. I have been probing this and I heavily suspect the problem might be from my frictional contacts. I am running a model with a lot of sheet metal parts hence I have a lot of frictional surfaces. Prior to this i had left them as frictionless but this gave me convergence issues especially with large defelctions turned on. Do you think I should surpress all my frictional contacts. is there a good substiture for this. In my 2022 R2 I had no convergence issues. On this solver i m also having scoping issues. Anytime i try to update my model on space claim and re import geometry other parts start to loose scoping or simply become unsurpressed and cause convergence issues. is there also a good solution to this as well or am i missing a setting.

Hi Kenneth,

As some default settings are changed with every version in order to improve the software performance such issues can happen. Can you please provide some images of the model, the error message you are getting, and the contact settings you are using? This will enable us to assist you more effectively.

Thanks,
