[Paraview] Fwd: Particle tracer

[Dan Lipsa]

Andy,
Thanks for your reply. For ParticleTracer there are 7 cells and 7 points
which is correct. My problem was that the velocity was too small so the
particles were moved a very small distance. Using a Calculator filter to
increase the velocity (using Leo Liu suggestion) allowed me to see the
particles moved by the filter.

ParticlePath and StreakLine still don't work for me (see my other email to
the list). Any suggestions would be greatly appreciated.

Thank you,
Dan
