Mehdi534 is on a distinguished road
In a steady state I simulate a passage of power turbine and diffuser by CFX. The aim is to calculate pressure recovery by diffuser. Unfortunately the pressure is not stable at diffuser inlet and therefore the pressure recovery also variates in a range. I have used stage inteface and in the connection interfcaces pressure, temperature ,... are tangentially averaged. I will be tankful for some help on this issue.

Regards, Mehdi
