Hello
I attached another file to see it, I know that we can not add contact pair in the step but I tried to define it before and it didn't work
the first step can run but the others no (when I add the liner tunnel)
thanks...
Hello colleagues
I've problem in case of defining interaction properties between soil end tunnel I changed properties and I tried to define the type of contact in steps but it's non working.
I think the problem it's due to the remove of my liner in the first step and add in it the second step...
