[yt-dev] Vorticity

[Matthew Turk]

Hi all,

I have been working with Jia-Hung on looking at vorticity in his GAMER
simulations.  He has supplied me with a dataset where the minimum
vorticity (by prescription) should be at the center.

After a lot of back and forth with him and with Jeff Oishi, I
determined that what looks to be happening is that unless I set the
number of ghost zones to 2 (instead of 1) there is a systematic
offset.

Can anybody think why this might be?

I'm working on making this into a unit test to check its behavior in 3.0.
