Hi,
I am trying to model a simple heat transfer experiment in 2D. However, I have never done that before and I urgently need some help.

Please find the jpeg file at the attachments. It clearly explains the problem. The fluid is air and the solid body will vary-I will try aliminium,copper,etc.

1-How to define boundary conditions for the interface? I use Gambit for meshing and defining the boundary conditions.
2-How to define solid body?
3-Which radiation model would you recommend?

Thanks.
