.Physiolibrary.UsersGuide.Connectors

Information

The Physiolibrary defines the most important elementary connectors in various domains. If any possible, a user should utilize these connectors in order that components from the Physiolibrary and from other libraries can be combined without problems. The following elementary connectors are defined (the meaning of potential, flow, and stream variables is explained in section "Connector Equations" below):

domain	potential variables	flow variables	stream variables	connector definition	icons
hydraulic (fluid)	absolute pressure	mass flow	enthalpy, substances concentrations	Modelica.Fluid.Interfaces FluidPort, FluidPort_a, FluidPort_b Fluid.Interfaces FluidPort, FluidPort_a, FluidPort_b
thermal	temperature	heat flow rate		Modelica.Thermal.HeatTransfer.Interfaces HeatPort, HeatPort_a, HeatPort_b Thermal.Interfaces HeatPort, HeatPort_a, HeatPort_b
population	the number of population members	change of the number of population members		Population.Interfaces PopulationPort, PopulationPort_a, PopulationPort_b
block diagram	Real unit-typed variables			Types.RealIO EnergyInput, EnergyOutput, TimeInput, TimeOutput, MassInput, MassOutput, MassFlowRateInput, MassFlowRateOutput, HeightInput, HeightOutput, AccelerationInput, AccelerationOutput, PressureInput, PressureOutput, VolumeInput, VolumeOutput, VolumeFlowRateInput, VolumeFlowRateOutput, ConcentrationInput, ConcentrationOutput, OsmolarityInput, OsmolarityOutput, AmountOfSubstanceInput, AmountOfSubstanceOutput, MolarFlowRateInput, MolarFlowRateOutput, DiffusionPermeabilityInput, DiffusionPermeabilityOutput, HeatInput, HeatOutput, TemperatureInput, TemperatureOutput, HeatFlowRateInput, HeatFlowRateOutput, ThermalConductanceInput, ThermalConductanceOutput, ElectricCurrentInput, ElectricCurrentOutput, ElectricChargeInput, ElectricChargeOutput, ElectricPotentialInput, ElectricPotentialOutput, FractionInput, FractionOutput, FrequencyInput, FrequencyOutput, OsmoticPermeabilityInput, OsmoticPermeabilityOutput, HydraulicConductanceInput, HydraulicConductanceOutput, HydraulicComplianceInput, HydraulicComplianceOutput, HydraulicInertanceInput, HydraulicInertanceOutput, GasSolubilityInput, GasSolubilityOutput, DensityInput, SpecificEnergyInput, SpecificEnergyOutput, SpecificHeatCapacityInput, SpecificHeatCapacityOutput

In all domains, usually 2 connectors are defined. The variable declarations are identical, only the icons are different in order that it is easy to distinguish connectors of the same domain that are attached at the same component.
