This model tests the inverse formulation of the flow functions.
The pressure difference dp
and dpCalc
need to
be equal up to the solver tolerance, except for a small neighborhood
around the origin. In this neighborhood around the origin, the functions
Buildings.Fluid.BaseClasses.FlowModels.basicFlowFunction_dp
and
Buildings.Fluid.BaseClasses.FlowModels.basicFlowFunction_m_flow
are not invertible.
