I’m new to YT. I encountered a problem when trying to plot the divergence and vorticity of a velocity field with an octree data structure similar to FLASH.
I put a cylindrically symmetric velocity field into YT. So far I could get Velocity Magnitude Plot correctly and the Velocity vector looks also fine (see the attachment). However, the VorticityMagnitude and DivV plots have a offset toward the top right corner. I was wondering where I did it wrong. Any suggestion will be welcome, and thanks for the help in advance.
New issue 797: Handling cell_volume in 1D and 2D cartesian
`cell_volume` is ill-defined for 1D and 2D cartesian data because it is still given in terms of length**3, even though the unused dimensions are meaningless. What we have done is set the `domain_width` to unity in these cases, but with the unit refactor I think this issue ought to be revisited.
That said, I'm not sure what to do about it.
I imagine someone here might have something to contribute.

I asked a few weeks ago for examples of 21st Century science to
include on our web site:

We've had a handful of entries so far, and I'd welcome more - please
ping me if you have something you'd like us to showcase for you.

New issue 795: ART particle data file recognition
yt is unable to automatically locate the particle data file when certain ART files are loaded.
pf = load('10MpcBox_HartGal_csf_a0.500.d')
yt : [INFO ] 2014-02-28 15:07:24,747 discovered particle_data:/hyades/karraki/yt/scripts/10MpcBox_HartGal_csf_a0.500.d
This only occurs with Sebastian's output files not Daniel's files.
If the full file names of each type are provided, the files load just fine.
We've had a couple critical bug fixes go in to the mainline 2.x branch
lately, and we're also slightly overdue for a 2.6.2. So I would like
to cut a release on Thursday. If there are any objections, let me
know, otherwise I'll proceed with merging into stable, tagging, and
uploading to pypi. John ZuHone pointed out that with Kacper's fixes
to the packaging and his fixes to various imports and whatnot we ought
to keep to this schedule; I've let it slip a little.
