Issue #1034: halo callback docstring issue (yt_analysis/yt)
by Nathan Goldbaum June 22, 2015

June 22, 2015

New issue 1034: halo callback docstring issue https://bitbucket.org/yt_analysis/yt/issue/1034/halo-callback-docstring-iss… Nathan Goldbaum: The docstring for the virial_quantities halo callback is incorrect. The docstring references a `critical_density` keyword argument, but the actual function signature contains a `critical_overdensity` keyword argument. While fixing this, it would probably be worth giving the rest of the docstrings in this file a once-over.

Feature Request: Create data set format mapper
by Joseph Smidt June 16, 2015

June 16, 2015

Not sure if it is better to request features here or on bitbucket so I am doing both [1]. I am doing some code comparisons between Enzo and Gadget and it would be nice if I could map an Enzo data set to Gadget and visa versa. And I am sure it would be nice if YT users could translate data sets between all codes YT can read. YT already reads in and transforms these data sets to match YT's internal structures. It would be a nice feature to be able to map one data set to another for code … [View More]

Issue #1032: Projection Plot Image Size Inconsistency (yt_analysis/yt)
by ggoodwin52 June 12, 2015

June 12, 2015

New issue 1032: Projection Plot Image Size Inconsistency https://bitbucket.org/yt_analysis/yt/issue/1032/projection-plot-image-size-… ggoodwin52: I use projection plots to generate images of my simulation marching through time, then combine the images into a video using mencoder. Attached is a sample script I use to generate the images and a sample video. You will notice in the video that the frame "oscillates" as it progresses, which is very distracting from the actual simulation. This … [View More]

VR refactor status update
by Matthew Turk June 10, 2015

June 10, 2015

Hi all, Andrew, Kacper, Allyson and I had a hangout to go over the current state of the VR refactor that Sam started. Where we're at: * Docs need to be written and updated. I have committed to taking this on, and I am starting today. * There are two cameras that need to be ported, the setreo spherical camera and the perspective camera. Suoqing, is there any chance you might be able to take a look at doing this, and issuing a PR to Sam's repository? I ask only because you've been so good … [View More]

Issue #1031: Bug Report: Memory leak when rendering projection plots in parallel (yt_analysis/yt)
by ggoodwin52 June 10, 2015

New issue 1031: Bug Report: Memory leak when rendering projection plots in parallel https://bitbucket.org/yt_analysis/yt/issue/1031/bug-report-memory-leak-when… ggoodwin52: I emailed this bug report out to yt-users before finding this repository, sorry for the double post. I believe I have found a memory leak when iterating through a DatasetSeries in parallel to render projection plots of each data file in the series. I work in a CFD research group and our code is built on boxlib, so I have … [View More]

Issue #1030: Document the enable_plugins function (yt_analysis/yt)
by Nathan Goldbaum June 9, 2015

June 9, 2015

New issue 1030: Document the enable_plugins function https://bitbucket.org/yt_analysis/yt/issue/1030/document-the-enable_plugins… Nathan Goldbaum: This function parses the plugins file and allows the fields and functions defined there to be used in a script that imports yt using `import yt`. It needs docstrings, to be present in the API docs, and needs to be mentioned in the documentation section on the plugins file.

GridsSource in vr refactor
by Matthew Turk June 7, 2015

June 7, 2015

Hi all, Anybody here know why with the scene refactor, no matter how low I set the opacity of the grids, they (villainously) blot out the sun? Here's a script: http://paste.yt-project.org/show/5608/ Here's the output of new_tf_clip.png: http://i.imgur.com/ZRTz4kR.png and now, what the script calls grids_overlay.png: http://i.imgur.com/fPvVDdP.png I mean, I *must* be missing something, right? -Matt

ramses length units
by Desika Narayanan June 5, 2015

June 5, 2015

Hey YT-dev, I've discovered something that I think could maybe be a bug (though maybe not) in the Ramses front end but am unsure about the motivation behind the code so thought I'd check in and try to learn a bit. In frontends/ramses/data_structures.py, I think the length_unit is set to be the length_unit that comes from the info_xxx.txt file multiplied by the box length. For the example yt data sets, this doesn't impact anything because the box lengths are unity. In examining some Agora … [View More]
