Default: 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 possible choices depend on the dispersion method selected with the LIBMBD_METHOD tag and are listed in the file mbd_damping.F90 of the libMBD source code. If LIBMBD_XC=none is chosen, then no set of damping parameters is selected and, instead, it is possible to set the parameters manually with the LIBMBD_TS_D, LIBMBD_TS_SR, LIBMBD_MBD_A and LIBMBD_MBD_BETA tags.
| 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.
