calculating torque
 
hi everyone, I have a question regarding calculating the torque on a turbine in CCM+, I know we can calculate lift and drag, but any idea about calculating torque?thanks

Torque = distance x force

torque
 
THANKS for the info, I know the formula but l am looking for a way to calculate the torque over a rotating part, using CCM+ features, any clue?

In Report, choose a moment report, you will have to define this about a certain point. You will then have to choose the surfaces which contributes the pressure+shear forces.

Torque is calculated by the integral of distance (from the point you defined in the moment dialog) times pressure over the surfaces concerned. Don't worry, this is done by the reporting tools of star-ccm+.
