I first need to perform a "Stationary" study ( first step) and then "Eigenvalue" study as the second step in a COMSOL model. The Eigenvalue PDE will feed by the results of "Stationary" study. I...

Imagine, there are series of 2D results which must be complete using "parametric sweep" (e.g. set of {S(y, z)}, each " S" for one point in x direction). This means "Parametric sweep" has been done...
