LIBMBD MBD A: Difference between revisions

Latest revision as of 13:58, 19 March 2024

LIBMBD_MBD_A = [real]
Default: LIBMBD_MBD_A = 6.0

Description: LIBMBD_MBD_A sets the value of the damping parameter $a$ in the many-body methods as implemented in the library libMBD of many-body dispersion methods^[1]^[2]^[3].

LIBMBD_MBD_A allows to choose the value of the damping parameter $a$ in the many-body methods as implemented in the library libMBD of many-body dispersion methods^[1]^[2]^[3]. The value is internally passed to the libMBD input mbd_a described at the page ^[4].

Mind: LIBMBD_MBD_A can be set only if LIBMBD_XC=none.

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.
