Hi
well if you start with COMSOL you will have some reading, I had to read the books several times to feel comfortable with them, because there is really a lot of matter, in fact it's "all Physics" rewritten in COMSOl approach, with their conventions, not always 100% in line with my (now older) training habits, but its all crrect so it's just to learn it their way. But you will get there, and then it's really fun.
In any case, I must strongy suggest that you always verify your model calculations: do a simple thermal calculations for the heat exchange by an anlytical formulation, get your area, the two temperatures and then multiply by sigma the Boltzmann constant (with the correct power of T in Kelvin, and it's the difference of the T^4 in absolute temperaature and not the ^4 of the difference !) this you find in most thermal analysis books, do not forget to check your units.
This gives you the amount of heat exchange (if you are in 2D you must consider areas as length per meter "depth").
Good luck
