How can I join a "Stationary" and a "Eigenvalue" study in one COMSOL study?

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...

How to merge the results of a "Parametric sweep" applied to a 2D model to make 3D data in COMSOL?

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...
