[yt-dev] Question about vorticity and divergence plots

[Matthew Turk]

Hi Jia-Hung,

Interesting.  With cell-centered data, it ought to produce correct results.

Would you be able to send me a small sample dataset (off-list) and I
can take a look?  Or feel free to stop by our hangout at 11AM Eastern
and I can try it out there.

-Matt
