I can perform thermal analysis of a circuit board for temperatures. However, I'm wondering how I would simulate the circuit board being covered in some type of material that prevents it from overheating (and it could be covered either in an even X mm coat or it could be put into a block of the material of x by y by z dimensions). Would I just make a block around it in Solidworks for the second "block" scenario?
modeling a component and getting it to mesh might be difficult.
consider a thermal resistance or reducing the convection coefficient.
do a test on a sample before you go to your full model.
