heat transfer calculation
 

Hi,
I'm trying to calculate heat transfer within a solid and between solid/air due to conduction, convection, and radiation. It's a transient calculation. View factors from one part of the solid surface to another part should be calculated separately before simulations, and should be set as initial conditions (or as geometrical data) to calculate thermal radiation within the body.
Does anyone know how to do it? Can OpenFoam calculate view factors?
If you know literatures of similar calculations, would you please let me know.
Thanks,
