Hello!

I want to visualize the result of flow velocity measurements in a flume with an obstacle.
We measured the velocities at 4 cross sections (x1,x2,x3,x4) and some 20-50 velocity points per section (Y-Z-rasterwise). Additionally, the water surface was measured with higher resolution (at 8 points). Now I want to interpolate the measurements to a finer mesh inside of the waterbody, i.e. the water surface should be the upper border.
By now it looks best with a 2D-Delaunay Filter for the surface and a 3D-Delaunay for the velocities - but I didn't find a way to clip (or whatever: define a query, calculation...) the volume to the surface. Example data is attached.

Does anybody of you know a way to do this in ParaView? Or would you recommend to do the interpolation with another programm (e.g. R)?

Thanks
Tom

(I know the experimental setup is everything else than very intelligent, I can't change it anymore . Anyhow, the solution would be interesting.)
