modelInverseFlowFunctions

Test model for flow function and its inverse

Extends from Modelica.Icons.Example (Icon for runnable examples).

Information

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 AixLib.Fluid.BaseClasses.FlowModels.basicFlowFunction_dp and AixLib.Fluid.BaseClasses.FlowModels.basicFlowFunction_m_flow are not invertible.
