Eigenvalue as coefficient in time-dependent PDE in COMSOL

I'm solving an eigenvalue problem in COMSOL. And after this, I'd like to use the eigenvalue as a coefficient in different physics. Thus, does anybody know what name stands for eigenvalue in Coefficient Form PDE in an eigenvalue study COMSOL? I expected something like u.ev but there is no such an attribute. Equation view shows only domflux.ux, domflux.uy, domflux.uz.

Also I've found c.omega. Is it the same as an eigenvalue?

Solution

  • In case of PDE, according to COMSOL Referecnce Manual:

    After solving an eigenvalue problem, the eigenvalue is always available for postprocessing under the variable name lambda, independently of whether the problem has been specified using the ea and d a coefficients or using the variable lambda.
