LIBMBD_MBD_A = [real]
Default: LIBMBD_MBD_A = 6.0
Description: LIBMBD_MBD_A sets the value of the damping parameter in the many-body methods as implemented in the library libMBD of many-body dispersion methods[1][2][3].
LIBMBD_MBD_A allows choosing the value of the damping parameter 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.6.5.0 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.
