Inlet and outlet pipes at Junction X do not have the same stagnation enthalpy

A Warning message in AFT xStream

Full Message text is:

Inlet and outlet pipes at Junction X do not have the same stagnation enthalpy.

 

The stagnation enthalpy entering a junction should equal the stagnation enthalpy exiting, assuming no flow splits and an adiabatic junction. This warning tells you that the values differ. Results are likely incorrect, and may not represent a converged solution.
