Using the assembly form


I am trying to simulate with "piezolectric devices". Specifically, I would like to exert stress on a thin film in contact with a piezoelectric 3D block. The geometry is quite simple but in order to mesh the thin film using "swept" I have to use "assembly" finish form (if I am right).

The problem is that during the simulation, it seems that both 3D piezoelectric block and thin film does not interact in any way (i.e. stress is not exerted).

I have played with "contact pairs" and "indetity pairs" with no success ! I am getting desesperate.

Any suggestion ?

Thanks !
