Volume at constant temperature

Dear all,
I am using the heat transfer module to simulate heat flow through a rod. The rod is connected to a piece of copper that is held at a constant temperature. The problem is that Comsol only gives me the option of selecting surfaces to fix t a constant temperature, and not a volume. Does anyone know how to get around this problem? The rod and copper are joined to eachother with a union.
Thanks

Hi
If you force a constant temperature over a full domain (volume), you can as well ignore it and force a constant temperature at its interfaces.
Think over it, your copper part interacts with the external temperature over its' boundaries, it's not really physical to impose a constant temperature and then apply a diffusion type equation on the domain, it is about a writing 0=0, not the most useful equation, or ?

Good luck
