LRHFCALC = .TRUE. | .FALSE.
Default: LRHFCALC = .FALSE.
Description: LRHFCALC selects the decomposition of the exchange functional for calculations with the range-separated hybrids RSHXLDA or RSHXPBE functionals.
If LRHFCALC=.TRUE. the exchange functional is decomposed into short-range LDA (or PBE) and long-range Hartree-Fock for calculations with the range-separated hybrid RSHXLDA or RSHXPBE functionals.[1][2][3] The screening parameter is specified by means of the HFSCREEN tag.
The setting of the RSHXLDA and RSHXPBE functionals is shown at list_of_hybrid_functionals.
