IVDW_NL = [integer]

Default: IVDW_NL	= 1	for a GGA
	= 2	for a METAGGA

Description: IVDW_NL allows to select the kernel of the nonlocal van der Waals part of a functional (available as of VASP.6.4.0).

IVDW_NL=1 corresponds to the kernel of Dion et al.^[1] and IVDW_NL=2 to the kernel rVV10^[2]. Note that the kernel of Dion et al. contains one adjustable parameter (ZAB_VDW), while the rVV10 kernel contains two such parameters (BPARAM and CPARAM).
