◆ build()

void CoolProp::MeltingCaloric::build ( HelmholtzEOSMixtureBackend & H )

sample() probe + per-segment Chebyshev fits vs ln(p). Idempotent; sets built()==true on success.

bool CoolProp::MeltingCaloric::built ( ) const

inline

Definition at line 50 of file MeltingCaloric.h.

◆ curve_Tmin()

double CoolProp::MeltingCaloric::curve_Tmin ( ) const

inline

Minimum temperature on the melting curve (may be below the triple-point T for fluids like water that fold back, e.g. ~251 K for water). Returns 0.0 if build() has not completed successfully.

void CoolProp::MeltingCaloric::sample	(	HelmholtzEOSMixtureBackend &	H,
		std::size_t	n
	)

Walk the melting curve over [pmin, pmax] into raw (lnp, T, rho, h, s) samples. n>=8. EOS density/caloric come from update(PT_INPUTS,...).

bool CoolProp::MeltingCaloric::seed_for_hs	(	double	s_cache,

Find a (T0, rho0) seed for a target whose caloric values are expressed in THIS object's build frame (s_cache, h_cache). Returns false if no melting- line entropy intersection exists. Disambiguates multiple intersections by closeness in enthalpy.

std::optional< std::pair< double, double > > CoolProp::MeltingCaloric::stamp ( ) const

inline

The (a1, a2) alpha0 offset pair that was active when build() was called, or nullopt if build() has not completed successfully.
