Revisions

  • May 17, 2024, by Michael Wetter:
    Updated model due to removal of parameter dynFil.
    This is for IBPSA, #1885.
  • July 10, 2018, by Alex Laferrière:
    Removed ground heat transfer models so the example focuses on the boreholes.
  • February, 2018, by Damien Picard:
    First implementation.
