zero Kelvin
 

Hi! i'm trying a radiation model, with buoyancy. When i ran temperature solver without radiation and buoyancy, the temperature results appear sensible but when radiation and buoyancy are on, i got near zero Kelvin thermal distribution. :confused: Anyone with experience, could quickly point out obvious mistake which i might have overlooked? urgent, i got close deadline and not much time to debug on my own! :eek: tq!

Most probably something is wrong with radiation setup - all the heat goes from your domain via the radiation and you end with nearly zero temperatures.

Unfortunately I don't have any experience with radiation problems, so you'd better check the manual.
