	Extract the mole fractions of liquid (x) and vapor (y) given the bulk composition (z), vapor mole fraction and K-factors. More...
void	CoolProp::SaturationSolvers::successive_substitution_guessrho (HelmholtzEOSMixtureBackend &HEOS, std::vector< CoolPropDbl > &x, std::vector< CoolPropDbl > &y, CoolPropDbl &rhomolar_liq, CoolPropDbl &rhomolar_vap, const std::vector< CoolPropDbl > &z, int num_steps, double tol=1e-6)
	Refine a two-phase guess (x, y, rhomolar_liq, rhomolar_vap) in place by successive substitution at fixed (T, p): re-solve each phase density near its current guess, recompute the K-factors from the fugacity-coefficient ratio, and re-split via Rachford-Rice. Stops early when max |Δln K| across components falls below tol. Used to seed the second-order (Michelsen) PT phase-split solver from a cheap estimate. (Adapted from jakobreichert's PR #2720.) More...
bool	CoolProp::SaturationSolvers::guess_split_from_wilson (HelmholtzEOSMixtureBackend &HEOS, std::vector< CoolPropDbl > &x, std::vector< CoolPropDbl > &y, CoolPropDbl &rhomolar_liq, CoolPropDbl &rhomolar_vap, const std::vector< CoolPropDbl > &z, CoolPropDbl T, CoolPropDbl p, int num_steps, bool require_bracket=true)
	Seed a two-phase guess (x, y, rhomolar_liq, rhomolar_vap) from the ideal (Wilson) K-factor estimate at fixed (T, p) and refine it by successive substitution. The liquid phase is seeded at the incipient (heavy-rich) composition rather than the feed, so the split does not collapse to the trivial solution near the dew point. Returns false when the Wilson estimate places the feed outside its bubble/dew points (no two-phase Rachford-Rice root) or a phase density cannot be obtained. Used to recover a two-phase state that the TPD stability test reported as single-phase (CoolProp-zgpy). More...
