Hello everyone,


I've been running an analysis about Heating and Cooling from radiant heating panels. I have justed created Fluid Domain (which is room that contains air) then gave the B.C. ( Heat Fluxes, Radiation, Temperature.) The models that we used are ;

-k-e (standard wall function) (Momentum eq)
-DO (Radiation)
-Energy Model was on
-Also boussinesq buoancy effect was on,

Along the analysis, I monitor wall temperatures, volume average temperature etc.
So since I've started, the everythings is alright but at 700.iterataion suddenly something gone wrong and volume av.temp and wall temp, reduced to 90K then at the next iteration ıt rised up to 700K. As a result of this unexpected things the analysis was diverged. Now I'm wondering about, Where did this problem come? Does anyone tell me the reason? Is there anyone who could tell me the reason?

I'm vey glad to hear your answers, thanks for all reply
