Package Sources contains generic sources for fluid connectors to define fixed or prescribed ambient conditions.
Extends from Modelica.Icons.SourcesPackage (Icon for packages containing sources).
| Name | Description |
|---|---|
BaseClasses … | Base classes used in the Sources package (only of interest to build new component models) |
Boundary_ph | Boundary with prescribed pressure, specific enthalpy, composition and trace substances |
Boundary_pT | Boundary with prescribed pressure, temperature, composition and trace substances |
FixedBoundary | Boundary source component |
MassFlowSource_h | Ideal flow source that produces a prescribed mass flow with prescribed specific enthalpy, mass fraction and trace substances |
MassFlowSource_T | Ideal flow source that produces a prescribed mass flow with prescribed temperature, mass fraction and trace substances |
Model FixedBoundary defines constant values for boundary conditions:
Note, that boundary temperature, density, specific enthalpy, mass fractions and trace substances have only an effect if the mass flow is from the Boundary into the port. If mass is flowing from the port into the boundary, the boundary definitions, with exception of boundary pressure, do not have an effect.

FluidPorts_b | ports[nPorts] |
Defines prescribed values for boundary conditions:
If use_p_in is false (default option), the p parameter
is used as boundary pressure, and the p_in input connector is disabled; if use_p_in is true, then the p parameter is ignored, and the value provided by the input connector is used instead.
The same thing goes for the temperature, composition and trace substances.
Note, that boundary temperature, mass fractions and trace substances have only an effect if the mass flow is from the boundary into the port. If mass is flowing from the port into the boundary, the boundary definitions, with exception of boundary pressure, do not have an effect.

Models an ideal flow source, with prescribed values of flow rate, temperature, composition and trace substances:
If use_m_flow_in is false (default option), the m_flow parameter
is used as boundary pressure, and the m_flow_in input connector is disabled; if use_m_flow_in is true, then the m_flow parameter is ignored, and the value provided by the input connector is used instead.
