packagePartialAlloy
Partial material properties (base package of all material packages)
Extends from Modelica.Media.Interfaces.Types (Types to be used in fluid models), Modelica.Icons.MaterialPropertiesPackage (Icon for package containing property classes).
Information
PartialMedium is a package and contains all declarations for a medium. This means that constants, models, and functions are defined that every medium is supposed to support (some of them are optional). A medium package inherits from PartialMedium and provides the equations for the medium. The details of this package are described in Modelica.Media.UsersGuide.
Parameters
