[Paraview] Surface streamlines are slow

[Bastil2001 at yahoo.de]

Hi group,

I tried creating some surface streamlines as described in the wiki.
Process seemed to work but was extremly slow for me so I could not wait it.
I have large CFD models imported as ensight (~ 20 Million cells).
Paraview run for about five hours without an result for surface
streamlines from 50 seed points. I don't really know if this is normal?
