IVDW_NL
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).
