Which is correct: Surface-to-Surface Radiation or Thermal Contact?

Please login with a confirmed email address before reporting spam

Which result is correct, please? The Thermal Contact setting seems to overwrite the Diffuse Surface at the contact?

  • I'm using Surface-to-Surface Radiation Multiphysic for metal/glass heat transfer.
  • I obtained 2 different results for including and excluding Thermal Contact setting: Heat Transfer in Solids > Thermal Contact > Constriction Conductance > User Defined > 1000 W/(m^2.K)

Please see attached screenshots and COMSOL file. Thank you very much!
