Hi Ilias, For the file.list, you could modify the script below, in order to circumvent, writing too mainy files in the "file.list" *--------------------------------------------------------------------------------* program lst1 implicit none integer, parameter :: N = 140 character*80,dimension(N) :: filename integer :: i,j,k open(unit = 10,file='file.list',action='write') write(10,"(I3)") N do i = 1,N if(i .lt. 100)then write(filename(i),'(A,I5.5)') 'turbChannel0.f',i else write(filename(i),'(A,I5.5)') 'turbChannel0.f',i endif enddo do i = 1,N write(10,*) trim(filename(i)) enddo close(10) stop end program lst1 *--------------------------------------------------------------------------------* For various post-processing format I use this script to write multiple files in file-list. I was previously using ifreguo = .true. in post-processing format of nek for uniform interpolation. But, how are you performing FFT after interpolating to uniform mesh. Are you using a library, could you elucidate/ describe a little more on the process, on how you do that? I was trying to do that as well.

For time-space Fourier analysis I need data on a uniform mesh. So I have used int_tp.
When I applied int_tp to binary *0.f* files (param(66) = 6) I have got a strange pictures which reflect the solution, but as if some elements were switched before interpolation.
So I tried to make uniform interpolation to the most simple tutorial examples, namely Rayleigh-Bendard ray_nn case.
Again if I apply int_tp to binary *0.f* of *fld*, then the result is as if the some space patches where switched, but if int_tp is applied ot ASCII fld files (param(66) = 6) then int_tp works and saves the result correctly to both text and binary format.
Is it a common problem, or I miss something? (input files in text format work for me but occupie too much space.)
Also, for each file in file.list int_tp asks for input file format. But to make time-space analysis I need more that 1000 files in file.list, and it is tiresome to type an answer that number of times. It could be better to choose input file format just once at the beginning?
Thank you in advance, Ilias
