Diverge with Radiation model in HVAC !
 
Hello everyone.

I should use radiation model in a case in order to set radiation emissivity to the walls. when I run without any radiation model, then I have no problem and I got a very smooth converge. But when I use the radiation model and use P1 or Rosseland, then I got diverge!
I try to run without radiation model to have an initial solution, but again I got diverge! I don't know what should I do!!
Anybody here knows what is the problem?!
Thanks

Try to refine mesh

Hello asal,
are you sure that P1 or Rosseland are the best models for your system?
