This section combines all possible additional dispersion corrections to the normal XC functionals. This can be more functionals or simple empirical pair potentials. [Edit on GitHub]

POTENTIAL_TYPE: enum = NONE

Aliases: DISPERSION_FUNCTIONAL

Usage: POTENTIAL_TYPE (NONE|PAIR_POTENTIAL|NON_LOCAL)

Valid values:

• NONE No dispersion/van der Waals functional.

• PAIR_POTENTIAL Pair potential van der Waals density functional, including Grimme’s empirical DFT-D methods.

• NON_LOCAL Nonlocal van der Waals density functional; more rigorous in principle, but significantly more time-consuming.
