ALDAX = [real]
| Default: ALDAX | = 1.0-AEXX | if LHFCALC=.TRUE. |
| = 1.0 | if LHFCALC=.FALSE. |
Description: ALDAX is a parameter that multiplies the LDA exchange functional or the LDA part of the GGA exchange functional.
ALDAX can be used as the fraction of LDA exchange in a Hartree-Fock/DFT hybrid functional.
| Mind: Note that for versions of VASP prior to 6.4.0, ALDAX was constrained to be equal to 1.0-AEXX. This constraint is lifted since VASP.6.4.0. |
