Can I have a semi-transparent wall with S2S radiation model?
1) Semi-transparent wall option under the radiation tab in wall boundary condition panel IS NOT available with S2S radiation, as S2S on calculates the radiative heat transfer based on view factors, and does not consider the medium participation
2) however, when the Solar Load model is switched ON with S2S radiation model, now an external or internal wall can be made semi-transparent to account for absorption, transmission & reflection of the radiant solar load at the surface.
