I want to find streamwise and normal vortices in cfd post. I see velocity curl in x y z direction. I am not sure if i am using the right variable. Does anyone know if they are same. I want to find using following formulas. how can i insert these into cfd post.

The variables have operators, such as gradients (and many others). Have a a look in the CFX Reference documentation for details. You can construct your formula from those.

Thank you, I found it. There were velocity gradients in each direction. Then I created expression using those.
