Torque is also available in the function library. In the option go to massflowavgabs and then calculate Total Pressure in Stn Frame for inlet as well as outlet. Regards Amit Roghs

In pre you prepare thse expressions. define monitor points in output control for these eqns. This will show their convergence in solver manager while running.and u can plot their output in Excel,also analyse them in post. Kumar.
