I am trying to find the axial velocity profile in a bend pipe ( where the adverse pressure gradient happens ). If I am using plot over the line filter, the U(magnitude) gives me a good velocity profile but it reflect the velocity which below zero to positive. So I can not see anything that below zero.

Is there a way to find the value of the axial velocity along a pipe?

Thanks
