Hello,

I am designing a building in front of a flow of atmospheric air around it. I wanted to model the sun's heat flux in 2D, but there seems to be no way to do it without the solar loads calculator, which is not available in the Participating Media model. The S2S model is not applicable in 2D.

I have tried to set a user defined wall heat flux cond A, leaving B,C,D zero and setting emissivity to one, environmental condition with zero heat transfer co-efficient.

Would really, really appreciate an answer, it's such a big headache.

Thanks!
