Revisions

  • January 10, 2025, by Michael Wetter:
    Changed tolerance of assertion blocks.
    This is for issue IBPSA #1952.
  • April 12, 2017, by Michael Wetter:
    Removed temperature connection that is no longer needed.
    This is for issue Buildings #704.
  • January 12, 2017, by Thierry S. Nouidui:
    Refactored difference blocks for checking integration errors. This is needed for the JModelica verification tests.
  • November 4, 2016, by Michael Wetter:
    Removed wrong use of each keyword.
    This is for issue 575.
  • 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.
  • October 24, 2013, by Michael Wetter:
    Set vol(h_start=45300.945). This avoids a cyclic assignment of vol.T_start and vol.h_start in Modelica.Fluid.Vessels.ClosedVolume.
  • October 12, 2009 by Michael Wetter:
    First implementation.
