Khelian973 New Member Kyian Barrat Join Date: Apr 2009 Posts: 25 Rep Power: 17	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
