IVDW_NL
IVDW_NL = [integer]
Default: IVDW_NL = 1 for a GGA or 2 for a METAGGA
Description: IVDW_NL allows to select the nonlocal van der Waals part of a functional (available as of VASP.6.4.0).
IVDW_NL=1 corresponds to the functional of Dion et al.[1] and IVDW_NL=2 to rVV10[2]. Note that the functional of Dion et al. contains an adjustable parameter (ZAB_VDW), while rVV10 contains two such parameters (BPARAM and CPARAM).
