How to view Vector Plot of Secondary Flow in Post?
Hi,
I'm hoping to investigate the secondary flow at a particular plane of my domain. However, I can't find the variable tangential Velocity, Vtheta for the vector plot in the Post 5.7. I use the cyclindrical vel components as inlet bc. Can anyone please tell me how to look at the tangential velocity component in Post? I only find Vx, Vy, Yz.... How to view Vtheta, Vr & Vaxial? Thanks a lot, Dan.

I just know when you creat a vector at the plane you specify, you can choose the vector projection parrmeter(none, tangential or normal on the plane) in this vector popup menu. if that's what you need?
good luck hannah 
Thank you
Hi Hannah,
Yes. That's what I'm after.... Thanks a lot.

hi
I have a project about it, until now i know that have to choose "tangential" in the vector part to viwe it? but i dont know if it is correct or not? also i want to know how much the wall can affect the secondary flow in the open channels(being small or big dimention of channel)? 
Dear colleagues,
I would need the tangent component of velocity along a 3D circular arc surface. Does anyone know how to get the tangent velocity as a variable and not necessarily presented as a vector plot? I am not sure the circumferential velocity variable calculated by the Turbo Post (in my case omega=0) can be considered as a reasonably good approximation of the tangent velocity. Best, Sal 
You can define a variable in CFDPost to be any function you like  so you can do the transformation into a tangential velocity about any axis you want. Also consider a local frame of reference, that may make things easier.

Thanks Glenn for your reply!
I am aware of that  I just wanted to know whether there is an easier way of doing it :)
