Hi Rahul,

 

Thank you for your suggestion!

I initially put surface-to-surface radiation inside the assembly like this

If I also put surface-to-surface radiation on the inner side, does it mean the room does not have a fluid movement? 

I tried changing the inner surface boundary into surface-to-surface radiation perfect enclosure instead of convection but it got an error in the boundary condition.

But if I also include convection at the same surface, the simulation runs

I was wondering why

Thanks 

 

Regards,

Ricardo
