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.


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: formalism.

Mind: Available as of VASP.6.6.0. Until VASP.6.5.1, the fraction of short-range exact exchange (when LMODELHF=.TRUE.) was fixed to 1 and could not be changed.
