Fluent Radiation/porous media

Schmitt pierre-Louis

Hi,

I'm now facing a big problem with fluent. I have to model a high temperature device wich comprises a porous media and a high temperature fluid zone. The problem is that by default a porous zone is considered as a fluid zone for the radiation and the radiation can pass trough the porous medium. It's not possible to consider that one side of an internal face participate to radiation and the other doesn't since it makes a bug during the computation and I can't define this interface as a wall since it will block the flow. There is also a problem using UDF since a UDF for special radaition can't be attached to any boudary condition exept a wall. Do you see a way to overpass this problem, or is it impossible. Thank you Pierre-Louis Schmitt
