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