Hello everyone!
I was wondering if there was any best way to get the FFT from a GridFunction in NGSolve?
Best,
Paul

Hm …
what do you assume from you mesh and your space ?
with structured meshes and Nodal-P1 you can take your coefficient vector and fead it into Python - FFT
otherwise, you have to evaluate your GridFunction on a regular grid of points (using geometric search) first.
