To do a subdomain integration with two different eigenvalue solutions

Mon, 08 Mar 2010 14:41:20 +0000

Hi,

I'm trying to do a subdomain integration with two different eigenvalue solutions, for example, with the first and the second one, but I don't know how to specify wich eigenvalue solution to use in the "Expression" field of "Subdomain Integration" window. I tried to use a second variable u2 with the same multiphysics settings, and then to put in the "Expression" field the first and the second solutions, e. g., u1*u2, but it seems that Comsol didn't store both solutions when in the "Solver Manager" I set "Solve For" just one variable.

What can I do to perform my task?

Thanks for help!
