[Paraview] Broken Streamlines

[Andy Bauer]

Hi,

You may want to try playing with some of the advanced options for computing
streamlines (click on the gear button in the upper right corner of the
parameters for the filter).

If that doesn't help, you may want to share your dataset so that we can
investigate. Also, is this a 2D simulation? It may be that the streamline
is going out of the plane of your grid and therefore terminating.
