Revisions

  • May 30, 2014, by Michael Wetter:
    Removed undesirable annotation Evaluate=true.
  • June 27, 2013, by Michael Wetter:
    Changed model because the outflowing radiosity has been changed to be a non-negative quantity. See track issue #158.
  • February 10, 2012, by Wangda Zuo:
    Fixed a bug in the temperature linearization.
  • February 8, 2012 by Michael Wetter:
    Changed implementation to use the same equations as is used for opaque walls.
  • August 18, 2010, by Michael Wetter:
    First implementation.
