Hi, I'm working on a time dependent heat transfer problem. At the end of each time step, I need to calculate some values based on the result from comsol solving nonisothermal model. I need to use the integral of Temperature Gradient along a wall for each time step, but there's no differential equation, just simple equations. Then I need to use one of the values I got to update my boundary condition for the next step, and store the other values I got.
Could anyone tell me how to make this happen? I tried adding mathematics opperator, but I didn't find a proper opperator that I can use. I've struggled on it for a long time. Didn't find the way I should do with Comsol. Any help will be appreciated please.
Thank you
