BEXX
BEXX = [real]
| Default: BEXX | = 1 | if LHFCALC=.TRUE. |
Description: BEXX specifies the fraction of short-range exact exchange in range-separated hybrid-functionals constructed with LMODELHF=.TRUE.
| Mind: Available as of VASP 6.6.0 |
| Important: Until VASP.6.5.1, the fraction of short-range exact exchange (when LMODELHF=.TRUE.) was fixed to 1 and could not be changed. |
The BEXX tag specifies the fraction of short-range exact exchange in range-separated hybrid-functionals. This tag can be used only when LMODELHF=.TRUE. More details can be found in the description of this class of hybrid functionals.
