LIBMBD_XC = [string]
Default: LIBMBD_XC = The functional set by the GGA, METAGGA or XC tag
Description: LIBMBD_XC sets the exchange-correlation functional for the setting of damping parameters used in the methods available in the library libMBD of many-body dispersion methods[1][2][3].
LIBMBD_XC allows to choose the k-mesh of the collective oscillations defined in the methods available in the library libMBD of many-body dispersion methods. The three integers correspond to the number of k-points along the axes of the cell in the reciprocal space. The values are internally passed to the libMBD input k_grid 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.
