Hi all,

I have a general question about the eigenfrequency setting in RF module.

there is a option as: Search for eigenfrequencies around:

In the past, I have used constants and explicit expressions with parameters, they works fine.

Now My intension is to narrow down the guessing of this start point for searching eigenfrequency, for example, a set of experimental results or semi-analytical results. But when I start to load an interpolated curve (function) for this option, the programe shows "fail to evalute the expression "

It seems there is some function definition problem here.

I'm not sure what's wrong with my setting?

I think this problem can be work around with livelink by setting the values in Matlab. But I don't know what's wrong with the COMSOL interface at the first place.
