Hi
I am simulating radiation heat transfer with comsol 4.0 which I start using today. Before I was using Comsol 3.3. I am simulating same model which I modeled on 3.3 and it did not give me any error. When I used same model ( I modeled from scratch in 4.0) with all same properties I am getting following error.
" Radiation error: exactly one adjacent domain must be opaque. "
I am not clear what cause this error..
Please advise
thanks

Hi
I havent had time to play alot with the radiatio physics in V4, but I noticed that there are many boundary condition settings, so I suspect that you have missed one (do none of your surfaces absorb ?) could this be it ?

Good luck
