Thanks a lot! I tried it before but it seems that the radiation flux will be zero when I do the post-processing. Should I turn on any radiation model in the solver?

Thanks,

HP Kritzinger,

Yes, the surface is on the outside of the domain. The surfice is exposed to ambient with temperature much lower than the surface temperature. I believe the radiation is equivalent...

Hello, I have a very basic question on the radiation modeling in fluent.

Suppose I have a solid body, and the surface is defined as convection and radiation BCs. The ambient temperature is fixed....
