Revisions

  • June 12, 2019, by Michael Wetter:
    Removed control volume in all junctions, as this leads to much faster simulation in JModelica.
  • January 22, 2016, by Michael Wetter:
    Corrected type declaration of pressure difference. This is for #404.
  • July 20, 2007 by Michael Wetter:
    First implementation.
