AMGGAC = [real]
| Default: AMGGAC | = 1.0 | if LHFCALC.FALSE. or AEXX1.0 |
| = 0.0 | if LHFCALC.TRUE. and AEXX1.0 |
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. |
