Calculating average velocity in paraview
 

Hello all,

I have imported the results to the paraview.
It's a simple 3-D cylinder containing gas and particles flow. The flow field has been solved in cylindrical coordinate.
At a specific height of the cylinder I would like to calculate azimuthally-averaging velocity for every point in the radial direction.
Could anyone please tell me how to calculate the azimuthally-averaging velocity and plot it against radius of the cylinder?

Cheers,
Reza
