Release Notes for Hydraulics Library 4.7

Hydraulics Library 4.7 is part of Modelon’s 2017.2 release.

New versions of Modelon libraries are sold and distributed directly from Modelon, as well as approved resellers.

New features

• Implemented a more flexible port-concept in Hydraulics. This is a substantial improvement to the ThermoHydraulics as it generates much more efficient system of equations due to no extra restrictions requirement just to avoid non-linear systems.

• Added more commonly used predefined medium models. They are based on real data sheets and appropriate references are included. All of these newly added media are compatible with ThermoHydraulics.

Improvements

• Updated heat exchanger with respect to new parameterization in Modelon Base Library.

Fixed issues

• Fixed documentation in Hydraulics.Fluids.Utilities.tempWeightCoefficients.
