LUSE VDW
LUSE_VDW = [logical]
Default: LUSE_VDW = .FALSE.
Description: The flag LUSE_VDW determines whether the VdW-DF functional of Langreth and Lundqvist et al. is used or not.
For gradient corrected functionals, generally variants of the VdW-DF functional of Langreth and Lundqvist et al. are used, whereas for SCAN and RSCAN, the rVV10 vdW-DF functionals are selected instead of the variants of Langreth and Lundqvist. The section linked above explains both variants.
