Hello,
I'm currently modeling heat transfer by using only radiation.

the geometry is complicated but i can say it's like Two concentric cylinders.

the inner cylindre generat the heat by Joule effect. and normally the outer cylindre has to warm up.

Because of electromagnetic issue, the fluid between the inner and outer cylindre is vaccum.

I already know that for S2S model I have to modele the fluid between the cylinders to let fluent calculat the view factors.

but i don't think that DO model needs the fluid, so can i just model just the two cylinders.

thank you for your help
