HI could any1 help me on how to assign pitch and yaw angles in fluent while running a simulation over a 3D wing. I want to assign both these values at the same time..

Let say fuselage is in XY plane and wings along the Zdirection. In this case logntitudal axis is X and vertical one is Y. The Zaxis is pointing out of XY plane.
Pitch angle = alpha Yaw angle = beta Formulae are: Case 1: Only alpha (Beta = 0) X = Cos (alpha) Y = Sin (alpha) Z = 0 Case 2 : Only Beta (Alpha = 0) X = Cos (Beta) Y = 0 Z = Sin (Beta) Case 3 : Both Alpha and Beta (360 model) X = Cos (alpha) cos (Beta) Y = Sin (Alpha) Z = Cos (alpha) sin (Beta) http://en.wikipedia.org/wiki/Axisangle_representation http://en.wikipedia.org/wiki/Yaw,_pi...93Bryan_angles http://en.wikipedia.org/wiki/Flight_...wing_aircraft) Last edited by Far; May 17, 2012 at 05:11.

Thank you for the reply...it was really grateful..I wanted to ask you of where to apply these formulas.. in the boundary conditions while setting the inlet velocities or at any other place,,,
