LIBMBD N OMEGA GRID: Difference between revisions

Latest revision as of 13:57, 19 March 2024

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.6.4.3 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.
