Issue #1172: ParticlePlot does not work on filtered particles (yt_analysis/yt)
by Yi-Hao Chen Feb. 22, 2016

Feb. 22, 2016

New issue 1172: ParticlePlot does not work on filtered particles https://bitbucket.org/yt_analysis/yt/issues/1172/particleplot-does-not-work… Yi-Hao Chen: If ParticlePlot is fed with a filtered particle field, it will read the filtered field and try to apply the filter again. I am not sure where the bug is, but at least it affects the ParticlePlot. The bug can be reproduced by the following script derived from the cookbook. ``` import yt from yt.data_objects.particle_filters import … [View More]

radiation groups
by Michael Zingale Feb. 22, 2016

Feb. 22, 2016

Is there a standard in yt for how to store radiation energy groups (e.g., nu and dnu) and a naming convection for radiation energy groups? (just worry about photon for the moment, but eventually neutrinos too, I suppose). I'd like to make sure any hacks I do in BoxLib are compatible with other codes. -- Michael Zingale Associate Professor Dept. of Physics & Astronomy • Stony Brook University • Stony Brook, NY 11794-3800 *phone*: 631-632-8225 *e-mail*: Michael.Zingale(a)stonybrook.edu *… [View More]

Issue #1171: Yt assumes matplotlib._png takes 5 arguments, but it takes only 3 (yt_analysis/yt)

New issue 1171: Yt assumes matplotlib._png takes 5 arguments, but it takes only 3 https://bitbucket.org/yt_analysis/yt/issues/1171/yt-assumes-matplotlib_png-… Anonymous: Matplotlib version: '1.5.1' (most updated on conda) Yt version: '3.2.1' (most updated on conda) matplotlib._png() does not take 5 arguments anymore, as is assumed in png_writer.py. This gives the following error when calling functions, such as cam.snapshot('myim.png'): ... return write_bitmap(out.swapaxes(0, 1), … [View More]

GSoC
by Matthew Turk Feb. 12, 2016

Feb. 12, 2016

Hi folks, In the past we've explored doing Google Summer of Code, but without much success. I think this year the time is right, and we should get set up to do so. The timeline is here: https://developers.google.com/open-source/gsoc/timeline?hl=en We have until the 19th of February to prep our application; I don't think we should go in as a mentoring organization, but instead attempt to apply through a larger mentoring organization such as NumFOCUS. Is anyone willing to be a mentor? This … [View More]

Issue #1170: Particle deposition for datasets without particle mass (yt_analysis/yt)
by Yi-Hao Chen Feb. 9, 2016

Feb. 9, 2016

New issue 1170: Particle deposition for datasets without particle mass https://bitbucket.org/yt_analysis/yt/issues/1170/particle-deposition-for-da… Yi-Hao Chen: Currently most of the particle deposition fields require the existence of "particle_mass" to be used as a weighting field. However, some simulations do not have "particle_mass" in the particle data. For example, the passive particles in FLASH do not have masses. Adding deposited fields by calling ```add_deposited_particle_field``` for … [View More]

GSOC projects
by Nathan Goldbaum Feb. 9, 2016

Feb. 9, 2016

Hi all, Britton and I brainstormed a bit on possible GSOC proects. We came up with the following google doc that covers five ideas: https://docs.google.com/document/d/1A5o5epJD-P8bUJy77XTSLFxIzQuVveHTtidcgvH… If you're interested in mentoring any of these ideas, please put your name down next to the idea as Britton and I have already done. If you have any more ideas, go ahead and add them. Optimally we will have at least two mentors per project, in case one mentor needs to bow out. I will … [View More]

Google summer of code hangout
by Nathan Goldbaum Feb. 8, 2016

Feb. 8, 2016

Hi all, This year OpenAstronomy is going to try to apply as an umbrella organization for various projects in astronomy who want to participate in GSOC. They're interested in including yt, so for now I think the plan is to apply with OpenAstronomy and then fall back to either PSF for NumFocus if the OpenAstronomy application does not go through. There's more information about OpenAstronomy and the GSOC application here: https://docs.google.com/document/d/… [View More]
