This example demonstrates how to export an FMU with a flow resistance and a control volume. The FMU has an instance of Buildings.Fluid.FixedResistances.PressureDrop and Buildings.Fluid.MixingVolumes.MixingVolume.
The mass dynamics has been set to
massDynamics=Modelica.Fluid.Types.Dynamics.SteadyState.
