.Annex60.Fluid.Sources.Boundary_pT

Information

Defines prescribed values for boundary conditions:

• Prescribed boundary pressure.
• Prescribed boundary temperature.
• Boundary composition (only for multi-substance or trace-substance flow).

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 applies to 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.
