Model FixedAmbient_pt defines constant values for ambient conditions:

• Ambient pressure.
• Ambient temperature.
• Ambient mass fractions (only for multi-substance flow).

Note, that ambient temperature and mass fractions have only an effect if the mass flow is from the ambient into the port. If mass is flowing from the port into the ambient, the ambient definitions, with exception of ambient pressure, do not have an effect.
