Determination of material property through integral and eigenvalue

Please login with a confirmed email address before reporting spam

Hi folks,
Is it possible to determinate Material Property (Relative permittivity) through expression that includes integral of dependant variable( Electric Field ) and eigenvalue( lambda)?
I have an expression for relative permittivity : Epsilon = Function( eigenvalue==lambda, intop1(Ex,Ey,Ez)). On each iteration it would have different value.
Should I use Constrains for this purpose?
Does anybody know is it possible to do this with COMSOL?

Best,
Nina.
