Simple heat module problem

Hello,

I have been using COMSOL for a while now, but this is the first time I have had to use the heat transfer module. I could attach my model, but I feel the problem is simple enough not to require it. I have set a temperature to a certain surface which is in contact with another with a given starting temperature. I merely wish to plot the energy flux through the contacting surface as a function of time. As of yet, I have not found of a way to do this. Any help would be greatly appreciated.

Thank you,

Peter
