[Paraview] Streamlines with an octree/hierarchical grid

Good afternoon,

I am trying to generate streamlines on a solution generated on an octree
style grid with hanging nodes/faces. I have cell centered data. The problem
is that the streamlines always end too early. I assume this has to do with
the incomplete connectivity inherent within this type of grid.

My questions is, has anybody dealt with this before? And if so, what might
I try to get this to work?

I've tried creating a 3D Delaunay tessellation from the cell centers
(obtained from the Cell Centers filter) but, at least for this case,
Paraview crashes. Also, converting the cell data to point data does not
take care of the problem.

I've thought about attempting to interpolate my data onto a uniform
structured mesh and use that new dataset as the source for the streamline
filter, but I'm not sure how to go about doing that.

Does anybody done this before or have any ideas about how I might solve
this problem?

Thanks for your time,

Ethan Alan
