Hi @snelson,
this can be done by creating an output that gives you the forces and moments and then calculating the power (if you like) with the relation P=M\omega .
• P : power in Watt
• M : torque
• \omega: angular velocity which is known from the rotating zones.
Our Power User @1318980 already gave some good inputs on a wind turbine at least which you can look up here:
• Wind Turbine blade, fluid and structural optimisation using CAE (Part 1)
For tutorials in general I would recommend:
• Video tutorials and
• Interactive tutorials
If you need help or more information, please let me know.
Have a nice weekend!
