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×
Single (VASP.5) 3/2×
Single (VASP.6)
SingleN (VASP.6) 3/2×
Accurate
Low 3/2×
Medium 3/2×
High

where

with =ENCUT.

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