LIBMBD_MBD_A
LIBMBD_MBD_A = [real]
Default: LIBMBD_MBD_A = 6.0
Description: LIBMBD_MBD_A sets the value of the scaling factor in the Tkatchenko-Scheffler method[1] as implemented in the library libMBD of many-body dispersion methods[2][3][4].
LIBMBD_MBD_A allows to choose the value of the scaling factor in the Tkatchenko-Scheffler method[1] as implemented in the library libMBD of many-body dispersion methods[2][3][4]. The value is internally passed to the libMBD input ts_sr described at the page [5]. LIBMBD_TS_SR is similar to the VDW_SR tag that is used for the VASP implementation of the Tkatchenko-Scheffler method.
| Mind: LIBMBD_TS_SR 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[3] and compiled before VASP is compiled with the corresponding precompiler options and links to the libraries.
