NGZ

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:

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

where

[math]\displaystyle{ E_{\rm cut}=\frac{\hbar^2}{2m_e}G_{\rm cut}^2 }[/math]

with E_cut=ENCUT.

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