Leo, Thanks for the suggestion with the calculator filter. I was able to use it to increase the velocity and see the particles moving as they should (ParticleTracer). Just a small note here, I see an warning when I use the First Frame (0) button. The warning does not seem to have any ill effects however.
Warning: In /home/utkarsh/Dashboards/MyTests/NightlyMaster/ParaViewSuperbuild-Release/paraview/src/paraview/VTK/Filters/FlowPaths/vtkParticleTracerBase.cxx, line 1372 vtkPParticleTracer (0x6a93c50): Can't go backward I still had no luck with the ParticlePath filter. I follow the same steps as for the ParticleTracer but the Information box shows me 'Number of Cells': 0 and 'Number of Points': 7 and no points or traces are displayed. Do you have any suggestions on what might be wrong with the ParticlePath filter. For the StreakLine filter the number of cells is 7 and number of points is 7 which seems correct. However no tracing of streaklines happens either. Paraview goes very fast through the time steps when I press the Play button (the same as for the ParticlePath filter). Do you have any suggestions for the StreakLine filter? Dan On Mon, Nov 19, 2012 at 9:06 PM, Yuanxin Liu <leo....@kitware.com> wrote: > Yes. Please try to put the source at the high velocity region.
