Hello folks, I am working on building an ANSYS model to simulate the effect of solar radiation on the thermal condition of a room. So I built a shoebox model. THE radiation model I used was DO model and solar ray tracing. The walls are opaque and the glass is semi-transparent. As shown in the first figure below, the patch of solar heat flux is normal and realistic. However, when I examine the temperature, things get a bit odd. As seen from the second figure, the glazing portion has a very high temperature and I was not sure what is really causing it. So if I changed the glass to an opaque surface then I can get a realistic result.
Does anyone know what is causing this? I have been battling with it for a while and still no clue of what is happening. Thanks in advance for any help!
