Hi all,

I'm trying to quantify the rotational velocity of the flow at various axial locations along this pipe duct.

I've tried using CEL such as:

massflowave(Velocity curl.X)@UserSurface1

However this gives the vorticity not the rotationality of the bulk fluid per se.

Does anyone have any thoughts? Ideally I could use polar co ordinates but I cant seem to make that happen either.
