Hi Miguel, I'm working on adding a general fourier analysis toolbox to yt, but it is not yet complete. For right now, the quickest way to do a power spectrum using yt is to extract a covering grid (which gives a cubic volume with constant resolution), and then use numpy's FFT tools to convert to k space and average over shells in k space. If you'd like to try the fourier analysis module in yt, you can get the changesets from my dev fork of yt, https://bitbucket.org/jsoishi/yt I'd be happy to step you through it off-list, as it is not quite finalized yet, and nice things like automatic k-space shell averaging are not yet in there. Please let me know if you have any further questions. Jeff On Mon, Mar 12, 2012 at 10:31 AM, Miguel Angel González <miguelglezbol@gmail.com> wrote:

Hi,

I’m working in Enzo and I’d would like to know if it generates its own power spectrum or if I have to configure it.

Thanks.
