LRHFCALC = .TRUE. | .FALSE.
Default: LRHFCALC = .FALSE.

Description: LRHFCALC selects a decomposition of the exchange functional for calculations with the range-separated hybrid RSHX functional.

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

Mind:

By default, AEXX=1 for the RSHX functional, but AEXX can be set to another value.
Only LDA or PBE can be used for the short-range density functional part.
