you may try to first project the velocity vector on the surface, so
that the normal components are zero, then compute the *streamlines*
using this velocity field. I did this with a velocity field which was
defined as a cell data, and the results are good (at least in my
case...).
Hi Marzio
But is not it the purpose of the "Surface Vectors" filter that should be
applied to the input vector field before calling the Custom
StreamTracer? I don't know what this filter exactly does.
As I said to Berk in my last mail, my velocity field coming from Euler
computations was supposed to be tangent to the surface, but it has been
interpolated to the grid's nodes, so it's not cell data, and the quality
of the surface grid seems to be very important. Maybe I would try later
with some clean cell data.
Best regards.
