I'm making a thermal simulation of a LED light. I have imported heat sink geometry as a CAD file and added some parts with Comsol tools. In front of the circuit board and LED chips there is a polycarbonate sheet and some air in between. The air space in the luminaire is thus closed. No air can come in and out. How should I make the model to take into account this air space? See attached pdf-file
