.IDEAS.Fluid.Sources.BaseClasses.Outside

Information

This is the base class for models that describes boundary conditions for pressure, enthalpy, and species concentration that can be obtained from weather data, and that may be modified based on the wind pressure.

If the parameter use_C_in is false (default option), the C parameter is used as the trace substance for flow that leaves the component, and the C_in input connector is disabled; if use_C_in is true, then the C parameter is ignored, and the value provided by the input connector is used instead.

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.
