The liquid model is designed for incompressible liquid fluids. All thermophysical properties are calculated dependent on the specific enthalpy (h). Only the specific entropy (s) is dependent on the specific enthalpy (h) and the given pressure (p). The parameter liquidType defines the medium. All available liquids are listed in the User's Guide -> Substance Names. The interface and the way of using, is demonstrated in the Testers -> TestLiquid.
