thermal conductance problem

[paola84]

Hi,

I´m trying to simulate the cooling of plastic in an injection mold (I have started with a simplificated 2D). If I glue both surfaces (steel and plastic) the mesh is continuous but the problem is that they share nodes in the common line and I can´t define diferent initial conditions for the steel and plastic at this line. If I mesh the surfaces as in the file attached, the nodes are different but I define the contact pair (surface to surface) and a thermal conductance (0.01) and there is no heat transfer between them.

If someone can help me...

Thank you very much.

Hi,
there simply isn't any contact pair defined in your model...
