Help me in finding/claculating flow angle after analysis of centrifugal impeller.

use vector and stream line in the cfx post.

Hello,
in my case I have two vectors in a 3D domain, respectively Velocity in Stn Frame and Axial Velocity, of which I want to calculate the angle between themself. What is the best way to do this? There is a function to calculate the angle?? I think it is not possible to play with simple sin,cos...
Help me.
Thanks a lot.

CEL has atn and atn2 functions. They can give you angles. Can do this is CFD-Post or in the solver with a monitor point.

How can I use this function? Suppose I have to find the angle of attack over a cross flow turbine then what expression should be used
