Hi all,

I am new to both c++ and channelflow so I would advice some patience. I am trying to extract the fourier coefficients in both x and z direction ( \hat u(kx,y,kz) ) which are function of y.

On channelflow 1.0, I think it would be u.makeState(spectral,physical), how can I achieve this in channelflow 2.0?

On Matlab, this would be equivalent to taking a 2D FFT of each slice of velocity in the y direction, but I would like to utilise channelflow 2.0 more and learn more about c++.

Cheers!
