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 exchange-correlation functional that determines which set of damping parameters is used in the methods available in the library libMBD of many-body dispersion methods. The value is internally passed to the libMBD input xc described at the page ^[4].

The

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.
