Hello, I am using Joule Heating Module to heat a 3D geometry. I have Al-metal and SiN4 above it, and Air, there voltage is applied to a metal (Al for this case), and I am trying to find effect of radiative heat-that is how much heat is radiated by Si3N4. In Heat Transfer in Solids I have selected surface to surface radiation and also added Diffuse Surface and selected Si3N4 and assigned emissivity as 0.88. Is this enough or is it correct to find radiative heat? I have attached png files to illustrate what I have done. Tnx

Hi Tohir,
No need to compute the air domain.
You can also neglect surface-to-surface radiation condition if you don't have radiative echange between surfaces. A simple diffuse surface condition with the ambient temperature can be used in your case.
