Absorption model
 

Hi Foamers,

Im working on a simply case : a room with a left wall at 1000K and a right wall at 2000 K. (the floor and the ceilin are adiabatic walls). I want to study heat transfert, with radiation. (so i use buoyantSimpleRadiationFoam). Im using OF 1.5 on Ubunto.
The solver runs but i have some questions about my inputs. Indeed i never defined the absorption coefficient of the walls. And it's important i guess.
Unfortunately I didnt find any reference in the userguide or here in the forum, but i saw there is an absorptionEmissionModel in the programmer's guide.
I would know if someone can help me on this case or know how to define absorption coefficient...
Thanks
Kyian
