In 2023 R2 the same project works fine, but after update to 2024 R1 i got this problem.

I have "pin" which connect two other parts - simple assembly, and pin indeed share one face with two parts, nothing special actually. SolidWorks and COMSOL also "think the same". But for some reason Ansys 2024 R1 (Mechanical) has another opinion. So why this happens and how i can avoid it or this is a bug and i need revert to 2023 R2 version?

Important note - all this contacts Mechanical creates automaticaly.

 

Many thanks for any suggestions.

Hi James,

Various defaults or additional choices are added to the solver with each release in response to reported errors and enhancements filed. Therefore, some of these adjustments may be causing some issues with your model.

What is the error you are getting? Can you share some more details about the issue so it will be easy to help you?

Thanks,

Its not error i thinkm because solving completed anyway. Im wandering how this behaviour can affect final results. For this small assembly its not a problem add split line to make exact contact-faces match. But in scope of entire construction this will create a lot of additional work. In same time COMSOL and SolidWork can handle shared contact-faces without problem.

Hi James,

Can you share some more details like contact settings, analysis settings, and results from the 2023R2 and 2024R1 versions? It will be easy to understand and help you effectively.

Thanks,
