    Corrected implementation of pressure drop calculation for the situation where the collectors are in parallel, e.g., if sysConfig == AixLib.Fluid.SolarCollectors.Types.SystemConfiguration.Parallel.
    Changed assignment of computeFlowResistance to final based on dp_nominal.
    This is for Buildings, #3597.
  • September 16, 2021, by Michael Wetter:
    Changed lat from being a parameter to an input from weather bus.
    This is for IBPSA, #1477.
  • December 17, 2017, by Michael Wetter:
    Revised computation of heat loss.
    This is for issue 1100.
  • November 21, 2017, by Michael Wetter:
