"fftw: fftw_malloc: out of memory" when running in 2D

[RSuryaNarayan]

It works perfectly well with 3D plotfiles, but I get the error in the title with 2-D ones.

[RSuryaNarayan]

Specifically it breaks off at L#701 AmrDeriveSpectrum.cpp while creating fft plans

[RSuryaNarayan]

Also, during compilation for 2D I get an error saying CONSTANTS.H was not found. I guess you meant AMReX_CONSTANTS.H instead.

[zingale]

probably. This code hasn't been used in a long while.

@zingale thanks. Is there any other feature/script with the same functionality as this one?

[zingale]

if you just want the power spectrum, then I've used yt for this in the past:

https://yt-project.org/docs/dev/cookbook/calculating_information.html#making-a-turbulent-kinetic-energy-power-spectrum

I'll take a look at this script when I have a chance though.

[RSuryaNarayan]

@zingale Thanks. I'll try that out. I am guessing the YT script works for any AMReX plotfile (as I'd be working with plotfiles from Pele and not CASTRO)
