IVDW_NL = [integer]
Default: IVDW_NL = 1 or 2
Description: LUSE_VDW=.TRUE. switches on the use of a nonlocal vdW-DF functional. These functionals depend on the electron density at two points in space and model long-range van der Waals (dispersion) correlation effects.
For LDA and GGA functionals (GGA tag), a variant of the vdW-DF functional of Langreth and Lundqvist et al. is used, whereas for the meta-GGA functionals (METAGGA tag), the rVV10 functional is selected. See nonlocal vdW-DF functionals for more details.
