Heat transfer to box

Heat transfer to box

Heat transfer to box

(OP)
Hi, I am new to FEMAP and was wondering if something like this is possible and how to do it: I want to be able to analyze the temperature of a "product" within a cardboard box+foam over time using a set ambient temperature profile (A degrees for X hours, B degrees for Y hours etc.). I also want to be able to change the thickness of the foam as well as add refrigerant(gel packs) inside of the box which would keep the inside cool. The ambient temperature would be created by an environmental chamber.

I am using the FEMAP v10.3 trial version and have found some useful things such as creating a temperature load that goes by a function, but I always get errors when I analyze that say "Unable to expand temperature from load definition "X" onto surface "Y". I feel like I am doing something wrong.

Can anyone help me? If you need more information, I can provide.
