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.
