Tarin is on a distinguished road
I am trying to simulate a continuously slipping wet clutch and initially I have simplified the problem to a rotating disc in contact with a stationary disc. I am using sliding mesh to do so with a heat generation rate defined in the shadow interface between the discs. The idea is to introduce the heat created by friction.

It seems to work OK when simulating the complete discs but I would like to simulate just a 30º sector (it is rotationally periodic) and here it comes the problem:

When defining “mesh interfaces” I select “Periodic repeats” and then I define the heat generation BC in the interface.

However when I simulate it, I see that the heat generation doesn’t work well when one sector move away from the other while rotating (I have done it with a very low rotating speed just to see what happens clearly)

I have tried defining the interface as coupled and periodic boundary but It doesn’t work and I don’t know how I should do it!

Please help me! I’m desperated!!!!!

Thank you in advance
