Hi,
I have tried to set up a contact problem for 2 different solid objects. When I tried to solve the problem, the following message will show up:
"Error: 7220
All variables solved for must be treated in at least one segregated solver step."
Can anyone advise me on how to tackle this error? Is there something I must do before doing a contact problem.
Thank you for your help!
John

I am also working on the contact recently. There is a very good model in the library, you can start from it.

Basically, you need to create a contact pair first, then try to play with the initial pressure and penalty factor.
