AMGGAC

AMGGAC = [real] 

Default: AMGGAC	= 1.0	if LHFCALC$=$.FALSE. or AEXX$\ne$1.0
	= 0.0	if LHFCALC$=$.TRUE. and AEXX$=$1.0

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

---

AMGGAC can be used as the fraction of meta-GGA correlation in a Hartree-Fock/DFT hybrid functional.

Mind: Note the difference with respect to AGGAC: AMGGAC multiplies the whole meta-GGA correlation functional, while AGGAC multiplies only the gradient-correction term of a GGA correlation functional.
