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}

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

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