WOLFRAM SYSTEM MODELER
Boundary_pTBoundary with prescribed pressure, temperature, composition and trace substances |
SystemModel["Modelica.Fluid.Sources.Boundary_pT"]
This information is part of the Modelica Standard Library maintained by the Modelica Association.
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.
