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×
Single (VASP.5) 3/2×
Single (VASP.6)
SingleN (VASP.6) 3/2×
Accurate
Low 3/2×
Medium 3/2×
High

where

with =ENCUT.

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