the axis is the axis vector that the force is computed relative to. i.e. you need to define which direction your lift/drag forces point in. Same thing with center of moment. Honestly you should already know these things if you know what lift,drag, and moment coefficient is... They're in the definitions. Do you even have any clue what you're doing?

hi luckytran
i had simulated a wind turbine in fluent and now i,m calculating it,s output power using torque.(report-forces-moment)
but what i earn in this way is 10 times bigger than real amount

would you plz help me?
