NGY

NGY = [integer]
Default: NGY = set in accordance with PREC and ENCUT

Description: NGY sets the number of grid points in the FFT grid along the second lattice vector.

By default NGY is set in accordance with the requested "precision"-mode (PREC) and the plane wave kinetic energy cutoff ENCUT:

PREC	NGY
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}

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