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×$G_{\rm cut}$
Single (VASP.5)	3/2×$G_{\rm cut}$
Single (VASP.6)	2×$G_{\rm cut}$
SingleN (VASP.6)	3/2×$G_{\rm cut}$
Accurate	2×$G_{\rm cut}$
Low	3/2×$G_{\rm cut}$
Medium	3/2×$G_{\rm cut}$
High	2×$G_{\rm cut}$

where

$E_{\rm cut}=\frac{\hbar^2}{2m_e}G_{\rm cut}^2$

with $E_{\rm cut}$=ENCUT.

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