I am simulating a thermal model for one theater in a steady state first, but found it is very slow to converge, and diverge easily.
After doing the steady state to obtain the general pattern of the internal environment, the further transient state simulation were done to see the result. Also quite easy to diverge.
Would like to study the reason and ways to solve this problem, though I know there should be lots of reason leading to the problem...

Thanks for the help!
