Hi all,

I'm working on a secondary flow induced mixing in a T-shape channel. I'm interested in calculating the cross sectional or transversal directional planar vorticity which I believe can lead to the secondary flow pattern. However, the channel is not straight, zigzag shape instead. The difficulty is how to obtain the planar vorticity value on a certain cross sectional plane which is not parallel to any axis, i.e, x, y or z direction. I can't find any solution in CFX POST so far. Could anyone share me some advice plz? thanks.
