NGZ = [integer]
Default: NGZ = set in accordance with PREC and ENCUT
Description: NGZ sets the number of grid points in the FFT grid along the third lattice vector.
By default NGZ is set in accordance with the requested "precision" mode PREC and the plane wave kinetic energy cutoff ENCUT:
where
with =ENCUT.
Alternatively, NGZ can be set to a specific value in the INCAR file.
