Hello guys,

I am studying the effect of wind vertical speed profile impacting on my object (a train pantograph) on the aero forces generated on its components.

To do this, i would like to plot the wind vertical profile with the y axis having its zero on the roof of the train, i.e. where physically there is the adherence condition, the velocity is zero and the boundary layer development is started.

I know how to extract the vertical profile through the ''plot over line'' command in paraview, now my question is:



Is it possible to plot velocity vectors departing from the same exact line used for the ''plot over line command''?



I think the best way to understand my goal is to look at the attached image where I roughly draw by hand what I would like to obtain.

Thanks to anyone who will spend his/her precious time to help me!
Cheers,

Luca
