Solid to solid thermal interface
 
Hello,

I am trying to simulate a geometry like this:

Heat flux applied to top walls
---------
Solid
--------- <-interface BC on each side
Solid
--------- <-interface or wall BC?
Fluid

I think I am having trouble with my boundary conditions. Each of my solids is its own volume and my fluid is also its own volume. I have defined interface boundary conditions on each solid face in Gambit. Im not sure if this is the correct way to do it. Then in fluent I couple them. I have my solid to fluid currently defined as a wall.

Also, I have multiple solids producing heat on top of a single solid which is then in turn cooled by the fluid. Would this effect my boundary conditions?

Thanks for your time!
