Revisions

  • December 22, 2014 by Michael Wetter:
    Removed Modelica.Fluid.System to address issue #311.
  • July 3, 2014, by Michael Wetter:
    Changed pressure sink to mass flow rate sink to avoid an overdetermined by consistent set of initial conditions.
  • March 25, 2008, by Michael Wetter:
    First implementation.
