[Paraview] Particle Tracer doesn't display any results

[Andy Bauer]

You probably need to glyph the output from the particle path and the
streakline filter to see the locations. Right now I don't think any cells
are being generated by those two filters. If you don't have any points,
you'll probably need to set termination time to something other than 0 for
particle paths. I haven't tested the streakline filter but suspect it has
similar behavior.

Regards,
Andy
