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: 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.
