[Paraview] Fwd: Particle tracer

[Yuanxin Liu]

Yes. Please try to put the source at the high velocity region.  You can
also use the calculator filter to increase the velocity.

Unlike the previous ParaView,  you don't attach another filter after
ParticleTracer to get path lines/streak lines.  Just use ParticlePath filter
 / StreakLine filter.  You can find a summary these features on page of 11
the Kitware Source July
issue<http://www.kitware.com/media/thesource/jul2012.html>.

 have recently made a number of changes to the particle tracing.  You can
find a summary on page of 11 the Kitware Source July
