LIBMBD XC: Difference between revisions

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 either LIBMBD_TS_SR or LIBMBD_MBD_BETA has to be set.

Important: This feature is available from VASP.6.4.3 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.
