I am trying to get a thermal model of air, say, in some air container as it is pressurized and de-pressurized. I know that I have to use the ODE solver to solve for the heat transfer by convection (for air) and conduction (through walls of container) for the modelling. Now, I am planning to conduct FEA for the same, and just to clarify, the temperature function would be from the heat transfer equation right? Also, if I had a code for a particular type of element of FEA, what would I have to be careful about when modelling for my case? I am confused, as in, I am not clear in the entirety of what I am supposed to do.
I am new to FEA, so please do give any suggestions/pointers you may have.
