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