Apply heat source on boundary
 

Hello,

First I'll explain the geometry.
I have 2 regions with 2 continua (solid and liquid) to model a coldplate with water flowing in it.

What I would like to do is to select a patch of the coldplate and apply the heat on that surface only which mean that in the region of the SOLID I have 2 boundaries (one passive and one active that generates heat).

My problem is that if I do that I don't know how to set up the Interfaces to have the correct heat transfer from the active coldplate boundary to the passive and then to the fluid. I know how to do it when I apply the heat to the entire region but not how to do it with the boundaries.

Any help?

thanks

Nevermind, my bad, I had the Solid Continua as "inative" in the expert properties (not sure why, missclick I guess) so the software was ignoring all my inputs on that solid
