Oops. I didn't notice that it was a "steady state" flow field. The
TemporalStremTRacer expects unsteady flows, however it would be quite
simple to modify it to use a single step. (I think easier than taking
streamlines and animating particles along them - though thinking about
it, the streamtracer code does have all that conversion of cell units
to time which would be useful).<br>
<br>
One could subclass the temporaltreamtracer, suppress the time requests
and interpolate over a single step, then output time dependent data
where the particles animate along the path (- how many steps would one
want?) - clicking the play button would just advect them along.<br>
<br>
(Just thinking out loud).<br>

<pre wrap="">I don't think this answers Pei's question. To my knowledge the
temporal stream tracer (i.e. particle tracker) works only for
time-dependent data. Am I wrong? To animate particles in a
steady-state flow field, I'd think that you would generate streamlines
and then somehow animate particles along those. I can't think of
anything that would do this out-of-box but writing a filter that does
this would be pretty easy. Is this something more than a few users
would want?

<pre wrap="">Hi Pei-Ying,
You may want to try ParaView Meshless
(<a class="moz-txt-link-freetext" href="https://twiki.cscs.ch/twiki/bin/view/ParaViewMeshless">https://twiki.cscs.ch/twiki/bin/view/ParaViewMeshless</a>). It is a
version of ParaView with the cutting edge of John Biddiscombe's
particle tracking work in it. Some of those features will be/have been
integrated into the main paraview code, but I can not vouch for when
that will happen.
cheers,
Dave DeMarle

<pre wrap="">Dear PVers:
I have a steady state flow field. I am wondering if PV can do particle
tracking animation.
what I am looking for is similar to pathlines, but, instead of showing the
lines, I would like to do an animation of seed particles "flowing" through
the flow field. Is this possible?
Thanks! and wish everyone here a Happy New Year!
Pei
