LIBMBD_METHOD = [string]
Default: LIBMBD_METHOD = mbd-rsscs (default in libMBD)
Description: LIBMBD_METHOD selects one of the methods available in the library libMBD of many-body dispersion methods[1][2][3]. Only used when IVDW = 14.
LIBMBD_METHOD can be set to a label (string) corresponding to one of the methods listed on the libMBD website (see method at the page [4]).
| Mind: Note that the use of the mbd-nl method[5] is currently not possible, since the associated atomic polarizabilities and semilocal functional are currently not implemented in VASP. |
| Important: This feature is available from VASP.6.4.3 onwards that needs to be compiled with -DLIBMBD. |
Warning:
|
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.
