 Dear Giovanni,
>That error should mean that you're using more cpus than the dimension of >the FFT grid along the z direction. Reducing the number of cpus should fix >the error. 
The error below remains even if I used only one cpu. Any idea?

 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     Error in routine  fft_type_set (6):
  there are processes with no planes. Use pencil decomposition (-pd .true.)
