Hi everyone, i am a beginner in CFD. I am doing a hydrokinetic turbine for my project and i have to do simulation on ANSYS CFX. I already find the RPM using when net torque is zero using the method i read in this forum (by varying the input angular velocity using steady mode). And now i want to find the coefficient of Torque for my turbine. And I want to do transient simulation to see the turbine rotating. The question is:

1) Should i use the RPM for net torque is zero (that i got just now) or I should find new RPM using transient simulation?

2) After run the simulation, there are different Torque at each time step. Is the optimal generated Torque is the maximum positive Torque?

I put together the screenshots from CFX Pre here so you guys can check if what i did in the setup is correct. Please help me, i've been stuck for a week now.

P/S: I am really a beginner sorry for the dumb questions. and also 've been looking for tutorial on youtube but most of them are for Fluent.
