wall heated by radiation
 
Hi everybody,

I played with the buoyantSimpleRadiationFoam tutorial, and it seems like fixedWalls are heated by the fluid, but not by the radiation itself.

I mean, the body should heat the closest fixedWalls directly by radiation.

I assume this behaviour comes from the zeroGradient condition applied to the fixedWalls for Temperature, so that walls take temperature they see from the fluid.

But is there any boundary condition for walls to be heated by surrounding radiation ?

Not sure I'm clear with my question, but any help will be appreciated.

Regards,
Fabien
