I am having trouble understanding how Fluent measures angles in the Cartesian coordinate system.

I need it to define 3 angles for a flapping wing system. FLUENT takes it as rotational velocities. When i use 2 angles, the behavior is fine but when a third angle is introduced, it goes haywire.

I doubt it whether the Eulerian transformations work the same way in FLUENT as in a general math case. Could anybody shed some light?
