KGAMMA = [logical]
Default: KGAMMA = .TRUE.
Description: Whether the automatically generated k-point mesh is centered at the [math]\displaystyle{ \Gamma }[/math] point.
If KGAMMA = .TRUE. (default), the k-point mesh is centered at the [math]\displaystyle{ \Gamma }[/math] point, i.e., it always includes the [math]\displaystyle{ \Gamma }[/math] point. If KGAMMA = .FALSE., the mesh is shifted away from the [math]\displaystyle{ \Gamma }[/math] point as in a Monkhorst-Pack grid. The number of k points on the mesh is controlled by KSPACING and KSPACING_OPT.
| Important: If a KPOINTS file is present, VASP ignores the KGAMMA and KSPACING tags. Likewise, if a KPOINTS_OPT file is present, VASP ignores KGAMMA and KSPACING_OPT. |
