Dear All ,
How to calculate the thrust from fluent for the rocket nozzle ?
Should i use Mass weighted_avg to get the velocity magnitude for calculating momentum and pressure thrust ?

Did you find way to calculate the thrust?
Please tell me because I am facing the same problem.......

I think the thrust of nozzles is caused by two types generally
1. Trust due to motion of the fluid mass
2. Trust due to difference in gauge pressure at the nozzle outlet
I think Mthrust(mass flow thrust) equal to: (Mass flow)*(Velocity_exit)
and Pthrust(pressure difference thrust) equal to: (Pressure_exit)*(area_exit)
