modelConductor
Hydraulic resistor, where conductance=1/resistance
Extends from Hydraulic.Interfaces.OnePort (Hydraulical OnePort), Icons.HydraulicResistor.
Information
This hydraulic conductance (resistance) element contains two connector sides. No hydraulic medium volume is changing in this element during simulation. That means that sum of flow in both connector sides is zero. The flow through element is determined by Ohm's law. It is used conductance (=1/resistance) because it could be numerical zero better then infinity in resistance.
