AGGAC

From VASP Wiki

AGGAC = [real] 

Default: AGGAC = 1.0 if LHFCALC.FALSE. or AEXX1.0
= 0.0 if LHFCALC.TRUE. and AEXX1.0

Description: AGGAC is a parameter that multiplies the gradient correction in the GGA correlation functional.


AGGAC can be used as the fraction of gradient correction in the GGA correlation in a Hartree-Fock/DFT hybrid functional.

Mind:
  • AGGAC is implemented for all functionals listed at GGA except AM05.
  • AGGAC is implemented for the functionals from Libxc (see LIBXC1 for details).
