LIBMBD_N_OMEGA_GRID = [integer]
Default: LIBMBD_N_OMEGA_GRID = 15 (default in libMBD)
Description: LIBMBD_N_OMEGA_GRID sets the number of points on the grid of imaginary frequencies used in the library libMBD of many-body dispersion methods[1][2][3].
LIBMBD_N_OMEGA_GRID allows to choose the number of points on the grid of imaginary frequencies used in the library libMBD of many-body dispersion methods. The value is internally passed to the libMBD input n_omega_grid described at the page [4].
| 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.
