Post-processing U field with fftw
 

Hi all,

I would like to perform a modal analysis on U field using FFTW 2.1.5 (from http://www.fftw.org/). My question is how can I link FFTW with a solver in OpenFOAM 1.6? And it's very important to be able to run it in parallel.

Thank you,
Pascal

i have seen the same topic about how to enter a fortran subroutine in openFoam, and the answer was to compile it as shared file (.so) but i myself dont know how?
