AMGGAX

From VASP Wiki

AMGGAX = [real] 

Default: AMGGAX = 1.0-AEXX if LHFCALC=.TRUE.
= 1.0 if LHFCALC=.FALSE.

Description: AMGGAX is a parameter that multiplies the meta-GGA exchange functional (available as of VASP.6.4.0).


AMGGAX can be used as the fraction of meta-GGA exchange in a Hartree-Fock/DFT hybrid functional (possible since VASP.6.4.0).

Important: AMGGAX can be used only if LHFCALC=.TRUE.
Mind: AMGGAX is implemented for the functionals from Libxc (see LIBXC1 for details).
