Andy,<br>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.<br>
<br>ParticlePath and StreakLine still don't work for me (see my other email to the list). Any suggestions would be greatly appreciated.<br><br>Thank you,<br>Dan<br><div class="gmail_extra"><br><br><div class="gmail_quote">

You may want to check out the information tab in the gui to see how many points and cells there are as the particle tracer iterates through the time series. By default I believe the vti files will assume a time step of 1 between files, which may not be appropriate for your velocity field and domain size.<br>

When I press play, the particles seem to stay in the same place. However, they do change color as they are colored by velocity magnitude. Maybe the velocity is very small and the particles don't move much - I trace only 43 time steps. I will try to trace the particles in an region of higher velocity tomorrow (is night here in UK). Do I need to apply another filter to get a pathline?</div>
