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 Ecut=ENCUT.
Alternatively, set NGX to a specific value in the INCAR file.
