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:

PREC NGX
Normal 3/2×Gcut
Single 3/2×Gcut
Accurate 2×Gcut
Low 3/2×Gcut
Medium 3/2×Gcut
High 2×Gcut

where

with Ecut=ENCUT.

Alternatively NGX may be set to a specific value in the INCAR file.
