This test checks if trace substance mass flow rates are conserved when steady state
Extends from IDEAS.Fluid.MixingVolumes.Validation.BaseClasses.TraceSubstanceConservation.
Information
This test checks if the trace substance flow rate is conserved
when adding moisture to a mixing volume that is configured to steady state.
The trace substance flow rate at the inlet and outlet should be equal
since the trace substance concentration should not
be affected by the independent mass fraction concentration.
Note, however, that there is some approximation error because in its default configuration, the conservation balance models simplify the treatment of the water that is added to the fluid. See IDEAS.Fluid.Interfaces.StaticTwoPortConservationEquation and IDEAS.Fluid.Interfaces.StaticTwoPortConservationEquation for a discussion.

Changed assertions to blocks that compute the difference, and added the difference to the regression results.
This is for issue 564. -
