• Keyword descriptions

  RC_RANGE
  	RC_RANGE {REAL}
  	Range of cutoff switch function (tapering): 0.5*(1-TANH((r-r0)/RC_RANGE)), where r0=2*RC_TAPER-20*RC_RANGE.
  	This optional keyword cannot be repeated and it expects precisely one real.
  	Default value: 0.00000000E+00
  	Default unit: [angstrom]

  RC_TAPER
  	RC_TAPER {REAL}
  	Atomic Cutoff Radius Cutoff for Tapering the screening term.
  	This optional keyword cannot be repeated and it expects precisely one real.
  	Default value: 1.20000000E+01
  	Default unit: [angstrom]
