Dear all I want to compute the DFT of a PDE solution. I have seen some Fourier Series in deal.II
https://www.dealii.org/developer/doxygen/deal.II/classFESeries_1_1Fourier.html and it says it is used to compute the DFT on the reference cell. I have seen examples of its use to estimate local smoothness of solutions. Can these functions be used to compute the DFT on the whole domain, e.g., to compute things like energy spectrum of a turbulent velocity field ? If this is not possible with these functions, do you have any suggestions how we can compute such spectra ?
