3D flow in fluent,Post processing
 

hello every one
I have modeled 3D flow in a curved pipe and I am trying to see secondary flow at different cross sections so I need to find stream lines,vectors the other stuffs that related to these kind of flows in 3D pipes with lots of curvature.
for example I attached a picture that shows one of these flow patterns.
Different kind of cross sections were made.I am using fluent 6.3.26 , I have tried this way
Display-vector-axial velocity-vector option-in plane

but it doesn't give the right answer.please help to find the solution.
thank you .
