Revisions

  • January 22, 2016, by Michael Wetter:
    Corrected type declaration of pressure difference. This is for #404.
  • June 5, 2015 by Michael Wetter:
    Removed annotation(Evaluate=true) from instances T_a_nominal and T_b_nominal to avoid the warning about non-literal nominal values. This fixes #128.
  • January 30, 2009 by Michael Wetter:
    First implementation.
