I would like to simulate heat
 
I would like to simulate heat transfer from circuit board components to the air inside the case, then to the case, and finally to the air outside the case.

I think I would need to use buoyantFoam but I have no idea how to deal with the heat transfer from the air to the case or heat flow through the case.

Any suggestions?

Hi,

You need basically for each phase (2 x air and solid) an own mesh. So things become a little complicated...

You can also use some kind of modified boundary condition. The choices you have are documented at:
