Calculating torque in a FSI wind turbine simulation
 

Hello everyone,

I have a question in which I have the feeling that it is more an issue of understanding the problem reather than the software itself.

I'm running a FSI transient simulation of a wind turbine. Wind goes through the blades, and the blades and the domain in which they are contained move (the complete domain is divided in 2, a rotor domain and an extranal one).

When it comes to calculate the rotated angle and velocity, there is no problem. But I would like to calculate the Moment (or torque) made by the turbine. I have tried to calculate it through a report, and with the Report function, and I get a value close to 0.

I understand that, since no resistance is oposing to the movement, there is no force made, but there is any way of calculating the torque in this particular problem??

Thank u so much in advance for your help. Regards,
Alex
