LIBMBD_K_GRID = [integer array]
Default: LIBMBD_K_GRID = determined in libMBD according to the cell shape
Description: LIBMBD_K_GRID is the shift for the k-mesh of the collective oscillations defined in the methods available in the library libMBD of many-body dispersion methods[1][2][3].
LIBMBD_K_GRID allows to choose a shift for the k-mesh of the collective oscillations defined in the methods available in the library libMBD of many-body dispersion methods. The value is internally passed to the libMBD input k_grid_shift described at the page [4].
| Important: This feature is available from VASP.6.5.0 onwards that needs to be compiled with -DLIBMBD. |
libMBD is a separate library package that has to be downloaded[2] and compiled before VASP is compiled with the corresponding precompiler options and links to the libraries.
