I have a model in which I would like to model contact between two domains. The physics of the model (boundary conditions etc) works just fine if I don't include the contact. Using "form union" at the end of the geometry sequence, the model behaves as I would expect. But if I wish to model the contact, I have changed this to "form assembly".

Having looked at a few tutorials and documentation, I know that I also need to set "create pairs" to true and set "pair type" to contact pair, then include the contact pair in the physics sequence. But this does not seem to be enough, as with these changes made, but with no other changes the model suddenly does not converge.

The converging model is attached as "g_p_reflow", while the broken model is attached as "g_p_reflow_ass".

Any suggestions?
