Interaction between soil and tunnel

[Taous]

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

Please if you can help answer me
thanks

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

It's the *.inp file extension that is the problem...
