Hi Rahul, 

Thank you for your prompt reply!

I wanted to clarify something:

  1. If I put convection on the outer side, do I have to also put convection as a boundary condition inside? (Otherwise the simulation won't run?). You previously suggested that I use perfect enclosure radiation to the inside surface as a boundary. But if I only put perfect enclosure radiation on the inside surface instead of convection, the simulation won't run.
  2. If I put a convection boundary on the inside, I must put in an "ambient temperature". What do you suggest I do if the ambient temperature inside is unknown? I know the default one from ANSYS is 22 degrees celsius and lots of other tutorials just leave it as the default. But does it mean we have to assume it?

Thank you, really appreciate your help
