[Paraview] Trajectories of material points

[Andy Bauer]

Is your data set a multiblock data set? If it is, you may need to have all
of the same point data fields ordered in the same way on each block. You
can use the pass arrays filter to get rid of all of the arrays that you
don't use if this is the case. Also, certain readers (the openFOAM reader
for example), has different arrays at the first time step than the others
and this can cause problems as well.

Can you share your data set? The particle paths filter can be a bit
finicky.
