[yt-users] Issue with ART tutorial

[Matthew Turk]

Hi Alex,

Sorry for the delay in replying -- what you've hit on is essentially a
major deficit right now (which came up on the yt-dev mailing list this
morning) which is that we don't currently have any comprehensive or
even consolidated documentation for yt 3.0.  The manner of handling
ART data has changed (for the better) and this is not reflected in the
current docs.  Chris Moody has long been in charge of the NMSU-ART
frontend, but I think with time that responsibility will migrate to
me, so I will continue editing and updating things.  Hearing reports
like this is extremely helpful, and it has already helped me identify
and fix a bug in the way cells were being filled for projections in
ART.  (Running "yt update" will get you this fix.)

I've prepared a notebook demonstrating some ART functionality in the
3.0 branch, and I've included in it some 3.0-ized versions of the
functions that the other email thread discussed.  In general, we're
attempting to make it much easier to interact particles with fluids in
3.0.  Note that I've divided by the cell volume here, so that the
visualization looks good; for doing other things like phase plots, you
likely won't want to do that.  You can view the notebook here:

https://hub.yt-project.org/nb/smmcsv

For some reason the Density field is resistant to automated logging,
so in the notebook I have manually logged it.

Let me know if that helps, or if there's anything else that you run into!

-Matt
