Information

This example demonstrates the use of the flow model with four different configurations. At steady-state, all flow models have the same mass flow rate and pressure difference. Note that addPowerToMedium=false since otherwise, Dymola computes the enthalpy change of the component as a fraction (k*m_flow+P_internal)/m_flow which leads to an error because of 0/0 at zero flow rate.
