AMGGAC = [real]
| Default: AMGGAC | = 1.0 | if LHFCALC[math]\displaystyle{ = }[/math].FALSE. or AEXX[math]\displaystyle{ \neq }[/math]1.0 |
| = 0.0 | if LHFCALC[math]\displaystyle{ = }[/math].TRUE. and AEXX[math]\displaystyle{ = }[/math]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. |
