How can I calculate power, torque, coeff of power and rpm of the vawt geometric parameterization of radius of savonius and height of darrieus so that I can get the suitable dimensions that gives max output power at constant air speed?

Is this an Ansys question?

[SUJAN DHAKAL]

Yeah I am using ansys fluent for the simulation but I got stuck in the setup/solution section on how to get the outputs 

[Federico]

You can set up report definitions for Moment and get torque and combine it with angular velocity to get power via a Named expression

When I tried to run simulation at constant air speed of 6 m/s the simulation gets stuck after certain iterations. What might be the problem?

[Federico]

You will need to provide more details to help us troubleshooting. What gets stuck? the convergence? the iteration? what does it say in the console?

[SUJAN DHAKAL]

Yes the iterations gets paused after certain iterations. I am new to ansys and this is my first project where I'm using ansys so I'm not much familiar with everything. Here's the setup setting I have set with the help of some YouTube videos. Can you please check if these are correct.

Finally my iterations ran completely but why the outputs are all zero can you check what might be the issue
