Comparison between numerical solution and Analytical expression - model verification

Please login with a confirmed email address before reporting spam

Dear Comsol Engineer:

How to make a transient model more accurate, how to output the real results, is it the reason for the time step of the solver? I am verifying the validity of the model. Although the trend of the results calculated by the two methods is consistent, the time when the numerical simulation solution and the Analytical expression reach the steady state is different, and the corresponding results of the numerical solution and the Analytical expression at different times are slightly different.

If you have any suggestions, I would greatly appreciate them.
