And so now the question: What do you want to achieve? You want to monitor the moment coefficient along two walls at a certain center and along a certain axis.nFluent Theory Guides describes the math behind that. n

i want to find the pitching moment coeffcient for wing. i just want to know if the points are r8 for the above conditionsn

If not elsewhere referenced for low speeds the aerodynamic center is at 0.25 of the chord length.You need to provide correct stream values in the reference values area or just get the moment around the center and then scale outside of Fluent n
