My case is that a 3d building situated within an air domain. I have done the solar calculation. I confused about How to set the thermal and radiation boundary condition of air walls. Opaque or semi-tranparent? I tried to select semi-transparent and set all the terms in transitivity section in 1, but I'm not sure is it correct? For the 3d building, I applied subtraction to remove solid body from the air domain, so finally only the surface of building left. I wonder how to work out the external emissivity and heat transfer coefficient if I put those thermal condition in the air wall. Another question is that if we assume a people inside the air domain, there must be a heat generation rate. What's the typical value of heat generation rate of people and for the mesh of people, do we just put a small-volume cube inside the domain and set each side with same heat generation rate?

Look forward to hearing from you

Thanks in advance

does anyone know how I can help CFD software (SOLAR LOAD, SOLAR RAY TRACING) computed flux of radiation absorbed solar parabolic dsih concentator in its focal plane of absorber spiral pipe receiver?

Thank you very much
