Hello,

I'm building a heat transfer model with two contacting domains: a copper cube and ice rod. The copper cube is a heat source and one end of the ice rod is contacting the cube and the temperature of the other end of the rod is constant. Therefore, the heat is generated in the copper cube and then flows to the right through the ice rod.

I'm using a time dependent study and get volume, surface or isothermal pictures but don't know how to get plots such as T vs. position at fixed times or T vs. time at fixed positions.

I also want to know how to deal with phase transition. I know I can use Heat transfer in fluid if I have only one domain for the phase change but don't know if I have two domains (copper and ice): when the temperature goes high, the copper cube will be still solid but the ice should melt.

I also don't understand how COMSOL deals with heat transfer through the contact boundary between the cube and rod. I don't have thermal contact boundary condition right now, but only have Heat transfer in solid through the two domains.

Thank you for your help in advance.
