.BuildingSystems.Fluid.MixingVolumes.Validation.MixingVolumeZeroFlow

Information

This model verifies whether the equations in BuildingSystems.Fluid.Interfaces.StaticTwoPortConservationEquation are consisent for all foreseeable cases. All MixingVolume instances contain the correct setting for prescribedHeatFlowRate. Switching the value will result in an error in each case. This error either is a non-physical solution to the (non-)linear system or a division by zero, which halts the simulation.

If you use Dymola, set Advanced.Define.AimForHighAccuracy = false to increase the chance of the error being produced for this simple example.

• January 27, 2016, by Filip Jorissen:
  Changed heat flow rate at zero flow to avoid triggering of conservation of energy check. This is for issue 470.
• November 2, 2016, by Michael Wetter:
  Removed assertion as the variable that are tested are already part of the regression test. Also, the previous implementation mixed graphical with textual programming, which we try to avoid.
  This is for issue 441.
• January 27, 2016, by Michael Wetter:
  Removed algorithm specification in experiment annotation.
• July 2, 2015 by Michael Wetter:
  Revised example.
• June 30, 2015 by Filip Jorissen:
  First implementation to test issue 282.
