Angle evaluation
Dear all,

I analyzed a pipe case for fluent. And, I examine uniformity and flow behavior for axial flow on cross section of pipe. The cross section is control surface for me.

For this control, I'm trying to evaluate phi angle on control surface about velocity vectors.

We can imagine that x is axial direction defined by axis of the outlet pipe, y represents tangential and z represents radial direction of cylindrical coordinate system.

My question is how I can define the angle form y (tangential) direction to the phi angle variation in range (-phi, phi) on post process of Ansys?

Does velocity angle contour plot cover it? Or, Should I write expression to create phi angles range for velocity vectors on control surface?

Thank you.
