Information

Model that tests the basic class that is used for the heater models. It adds and removes heat for forward and reverse flow. The top and bottom models should give similar results, although the sign of the temperature difference over the components differ because of the reverse flow. The model computes differences in results that are expected to be close to each other after the initial transients decayed. All temperature sensors are configured as steady-state sensors to avoid differences in temperature due to the dynamic response of the sensor.

Revisions

  • November 2, 2016, by Michael Wetter:
    Changed assertions to blocks that compute the difference, and added the difference to the regression results.
    This is for issue 564.
  • May 30, 2014, by Michael Wetter:
    Changed initialization of mass dynamics to avoid overspecified system of equations if the medium model is incompressible.
  • January 24, 2013, by Michael Wetter:
    Increased parameter startTime of the assert block and set initial conditions to Modelica.Fluid.Types.Dynamics.FixedInitial.
  • July 11, 2011, by Michael Wetter:
    Changed model to sensors with two fluid ports. Moved model to IDEAS.Fluid.Interfaces.Examples.
  • April 17, 2008, by Michael Wetter:
    First implementation.
