Hi All,
In my analysis, the convection heat transfer is very negligible compared to conduction and radiation. I am modeling fluid domain with the properties of air but I am defining it as a solid. I know that if I define a fluid domain as solid with air properties then conduction heat transfer will be accounted. If I want to calculate radiation heat transfer between the fluid surfaces (which is defined as solid) then how can I do it in FLUENT.

Thank you in advance
