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×Gcut
Single	3/2×Gcut
Accurate	2×Gcut
Low	3/2×Gcut
Medium	3/2×Gcut
High	2×Gcut

where

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

with E_cut=ENCUT.

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