Hello,

I have computed the eigenfrequencies and solutions of a 2D photonic system. I need to perform a two-dimensional Fourier transform on the solutions:

.

I am having trouble doing that computation on COMSOL. I know that I have to define a 2D grid for the parameters , and use the operator Integration (intop) on the domain of my geometry. But for some reason it is not working. Is there any other approach I could use? Thank you,

Jose H
