Default Gradient calculation in CFX

appu is on a distinguished road

I am working on a CFD problem in which i have to calculate the gradient of circumfernetial velocity on a plane inside the model. i tried using Circumferential Velocity.Gradient X,Y,Z options but the issue is the X,Y and Z values are calculated based on the global coordinate system.So it will not serve my purpose, as i require the gradient about a point in that plane. So how to get this done. Do i have to apply some transformation on the coordinate system.

Guys please suggest some ways of doing this. Thanks in advane.

You should be able to do a simple transformation of the Circ. Velocity.Gradient components to get the gradient components in a different direction.
