Hi everyone,
I'm new to Fluent heat transfer problems. In order to understand the solar load mechanism I've set up a simple simulation: a room of 2x2x1[m^3] with no roof. A solar ray tracing with irradiation 1100, diffuse 200, and spectral fraction 0.5 ,at an angle of 30deg to the horizon. I set S2S model (perhaps someone can also explain why without setting a model the wall temperatures rise up to 1500K) and an air inlet of 0.5m\s.
The final picture seems to make sense, but the wall temperatures are fairly high; ave temperature of about 90deg celsius.

Thank you!
