velocity on surface and Polyline

September 25, 2006, 09:14

hey,

On the surface of my Profil the velocity is Zero, but if I do a Polyline over the Profil and plot the velocity over the length (x) it is not zero. I think the Line is not equal to geometrie. I tried the polyline with

1. from a data file 2. boundary Intersection ( Plane with Profil)

but both didn't work.

Even if I set a Point on the Profil by X Y Z the value isn't zero.

What else can I do?

thanks for your help. Alex

Make sure the line is projected exactly on the surface. You should use the hybrid rather than the conservative value.
