This function may be used in order to calculate the thermodynamic state record used as input by many functions. It will calculate the missing states:

• density
• pressure
• specific enthalpy

Example:

parameter Medium.AbsolutePressure p = 3e5;
parameter Medium.SpecificEntropy s = 1.7e3;

Medium.SpecificEnthalpy h;

equation

h = Medium.specificEnthalpy(setState_psX(p, s, fill(0, Medium.nX)));

state = setState_psX(p, s, X, phase)

p	Type: AbsolutePressure (Pa) Description: Pressure
s	Type: SpecificEntropy (J/(kg·K)) Description: Specific entropy
X	Default Value: reference_X Type: MassFraction[:] (kg/kg) Description: Mass fractions
phase	Default Value: 0 Type: FixedPhase Description: 2 for two-phase, 1 for one-phase, 0 if not known

state	Type: ThermodynamicState Description: Thermodynamic state record
