modelFluidProperties

Model that tests the implementation of the fluid properties

Extends from PartialProperties (Partial model that contains common parameters of the fluid properties).

Information

This example checks thermophysical properties of the medium.

Revisions

  • June 6, 2015, by Michael Wetter:
    Changed type of T from Modelica.Units.SI.Temperature to Medium.Temperature. Otherwise, it has a different start value than BaseProperties.T, which causes an error if Buildings.Media.Examples.WaterProperties is translated in pedantic mode. This fixes #266.
  • October 16, 2014, by Michael Wetter:
    Removed call to setState_dTX as this function is physically not defined for incompressible media.
  • December 19, 2013, by Michael Wetter:
    First implementation.
