Eigenfrequency + parametric solver: how to find the eigenfrequncies

Please login with a confirmed email address before reporting spam

I've wrestled with this for quite some time by now.

I am trying to model a 2D (TE in-plane waves) photonic crystal and extract the eigenfrequencies of the system as a function of the incident k.

I choose the eigenfrequency analysis type.

When I also choose the eigenfrequency solver and solve for a single k value, I am able to get the eigenfrequency in postprocessing via the variable "nu_rfwe" using posteval.

However, when I switch to the parametric solver, I am not sure how to access the eigenfrequencies for each k parameter value. "nu_rfwe" or "lambda" don't seem to work, I always get a "cannot evaluate expression" error. The rest of the predefined quantities are just fine, e.g. I can plot the field values for any solution.

Any ideas here?
