NGX: Difference between revisions

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

Description: NGX sets the number of grid points in the FFT-grid along the first lattice vector.

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

where

E_{\rm {cut}}={\frac {\hbar ^{2}}{2m_{e}}}G_{\rm {cut}}^{2}

with E_cut=ENCUT.

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