Issue #858: Recently added particle fields don't put their deposit fields into the derived_field_list (yt_analysis/yt)
by Cameron Hummels July 17, 2014

New issue 858: Recently added particle fields don't put their deposit fields into the derived_field_list https://bitbucket.org/yt_analysis/yt/issue/858/recently-added-particle-fiel… Cameron Hummels: When one creates a particle filter, it successfully adds the derived particle fields to the derived_field_list, but it does not add the "deposit" fields to the derived_field_list (despite creating the fields).

Code freeze?
by Matthew Turk July 17, 2014

July 17, 2014

Hi everyone, Are there any outstanding, code-not-documentation issues other than existing pull requests that we need to get in before 3.0 goes out? If not, I'd like to propose a code freeze on the yt-3.0 branch in anticipation of the release, which I would like to shoot for happening by the end of July. Looking over Trello, the only thing that sticks out at me is boundary conditions, which I think needs to wait for 3.1. -Matt

website data page
by Michael Zingale July 17, 2014

July 17, 2014

Hi all, I am in the process of adding some Maestro and Castro datasets to the data webpage: http://yt-project.org/data/ I am happy to take the opportunity to reorganize it a bit, if people are agreeable. In particular, there are 3 separate tables on that page -- two seem like they could be merged: do we need a separate "yt sample data" and "yt 3.0 sample data" table still? Also, I'd like to sort the datasets alphabetically by data (front end) format, perhaps with a column-spanning header … [View More]

yt hub
by Cameron Hummels July 17, 2014

July 17, 2014

Hey everyone, Is there a timeline for the yt hub coming back up? I believe the hold up had been the fee of hosting the hub, which I think was being covered by Matt's personal funds. Is there ever any hope of getting some dedicated funds to support this in the future? If not, I'm happy to chip in some money to help this get back up. It seemed like a great resource both for hosting datasets and projects tangentially related to yt. Also, I think it was the location of the enzo test gold … [View More]

Gadget status
by Chris Malone July 16, 2014

July 16, 2014

Hi all, Caveat: I'm not that familiar with particle-based datasets/codes. I'm unsuccessfully trying to help a summer student do some visualization of someone else's Gadget binary data dump. What is the status of volume rendering SPH/Gadget data in 3.0? When I've tried what I know works for grid-based data, the returned image is simply empty. Projections look okay (for some variables), and Slices look worse as there are blank splotches, likely due to emptiness in the tree. Also, is there a … [View More]

Request for review: SDF
by Matthew Turk July 15, 2014

July 15, 2014

Hi all, The SDF pull request that Sam, Mike and I have been working on for a while is now ready for review: https://bitbucket.org/yt_analysis/yt/pull-request/955/wip-sdf-frontend-and-… The paper we put out that uses this and uses examples from it is here: http://arxiv.org/abs/1407.2600 (and you can see Sam use it right around here: http://youtu.be/ln4nE_EVDCg?t=19m47s ). It would be really great to get feedback and figure out what is necessary for this to go in. Thanks, -Matt

New issue 856: OffAxisProjectionPlot units set to 1 https://bitbucket.org/yt_analysis/yt/issue/856/offaxisprojectionplot-units-… Cameron Hummels: In OffAxisProjectionPlots, it appears that the units shown on the colorbar are set to `1` as opposed to the `projection_units` set in the field.

ART-NMSU particle mass units
by Kenza Arraki July 14, 2014

July 14, 2014

Hi, For ART particle data yt returns incorrect mass values. I believe this is something Matt had solved in March by dividing mass units by ng**3 for particle mass data. Miguel Rocha brought this to my attention and I have been able to reproduce the problem on the public ART dataset (D9p_500). http://paste.yt-project.org/show/4908/ I thought we had included the following in art/frontends/fields.py, but am unable to find it now. def setup_particle_fields(self, ptype): self.… [View More]

Hi all, The yt-fido is going to go down on 07/16 1:00am EDT due to network maintenance. Downtime may last even two working days, but I hope it will end sooner. Please keep that in mind while issuing PRs ;-) Cheers, Kacper
