modelMultiPhaseProperties
Extends from BaseMultiPhaseProperties.
Information
Model that calculates properties. For example of usage see MultiPhaseMixture.Information.UsersGuide.OverallProperties.
Balancing equations
In order for a model to be valid the user need to specify the value for 2 inputs + one composition vector. The input connector qualifier applied to p, h, and Z indirectly declares the number of missing equations, permitting advanced equation balance checking by a Modelica tool. For further information, see Section 4.7 (Balanced Models) of the Modelica 3.0 specification.
