Dev hangout summary
by Matthew Turk Jan. 16, 2014

Jan. 16, 2014

Hi all, Here are the things we talked about at the hangout, and where we left them: * There are two big things codewise for 3.0 -- the rebranding, and the unit refactor. We decided it would make the most sense to land the unit refactor first, wait a couple weeks, then land the rebranding. Neither are yet done, so this is still in the future a bit. * Documentation is widely viewed as the biggest impediment to 3.0 adoption. * Nathan is going to be sending around some info about a … [View More]

Issue #763: Covering grid does not get filled out for a tightly nested AMR dataset (yt_analysis/yt)
by Nathan Goldbaum Jan. 16, 2014

New issue 763: Covering grid does not get filled out for a tightly nested AMR dataset https://bitbucket.org/yt_analysis/yt/issue/763/covering-grid-does-not-get-f… Nathan Goldbaum: While I was helping Alex Bogert out with a visualization of my galaxy dataset, we noticed some odd behavior in the covering grid. This is exposed in the HiResIsolatedGalaxy dataset on yt-project.org/data using the following script: ``` #!python from yt.mods import * pf = load('HiResIsolatedGalaxy/DD0044/DD0044') … [View More]

Issue #762: Clump finder particles issue (yt_analysis/yt)
by Caroline Van Borm Jan. 14, 2014

Jan. 14, 2014

New issue 762: Clump finder particles issue https://bitbucket.org/yt_analysis/yt/issue/762/clump-finder-particles-issue Caroline Van Borm: When I try to run the clump finder on my Enzo dataset (using a script that mostly follows the find_clumps.py from the yt docs, but using a function to select gravitationally bound clumps), I get an error (see http://pastebin.com/bhmRs2R4). It seems that the clump finder is assuming there are particles in the simulation, even though there shouldn't be any. … [View More]

Hangout on Monday, January 13
by Matthew Turk Jan. 13, 2014

Jan. 13, 2014

Hi all, I'going to set up a (very low-key) hangout on Monday at 2PM EST just to have a brief catch-up on these topics: * Units * SPH * Scalability * State of documentation * My personal roadmap for next few weeks/months * Pending YTEPs and PRs * Other business For the most part, I plan to use this time to update others on my own progress on various things we've talked about here and elsewhere; I know that some other projects are blocked on my own progress, and I want to update people … [View More]

Issue #761: SlicePlot ".save()" stores image in plotfile directory, not current directory (yt_analysis/yt)
by Michael Zingale Jan. 11, 2014

Jan. 11, 2014

New issue 761: SlicePlot ".save()" stores image in plotfile directory, not current directory https://bitbucket.org/yt_analysis/yt/issue/761/sliceplot-save-stores-image-… Michael Zingale: When creating an image via "SlicePlot" of BoxLib data, the resulting image is stored in the plotfile directory, not the current directory. E.g.: pf = load("plt23437") SlicePlot(pf, 'x', "Density").save() creates the image "plt23437/plt23437_Slice_x_Density.png", when it should output simply to the … [View More]

Issue #758: VRs are transposed relative to projections (yt_analysis/yt)
by Cameron Hummels Jan. 4, 2014

Jan. 4, 2014

New issue 758: VRs are transposed relative to projections https://bitbucket.org/yt_analysis/yt/issue/758/vrs-are-transposed-relative-… Cameron Hummels: It appears that at some point the volume rendering interface underwent a transpose relative to the PlotWindow interface. When I make a simple VR with normal vector (0,0,1), that is, along the z vector, and compare it against a projection along the z vector, I get out two tranposed images. https://hub.yt-project.org/nb/gsob7g I know I have … [View More]

Update on Windows
by John Zuhone Jan. 1, 2014

Jan. 1, 2014

Hi all, Good news on the Windows/yt front. I'm happy to announce that as of right now only one unit test is failing. The failure is subtle, but I thought I would run it by you all to see what we should do about it. The failure in question is a comparison test in yt/utilities/tests/test_units.py, in "test_power": assert u2.cgs_value == (pc_cgs**2 * mK_cgs**4)**2 basically, the unit cgs_value is exactly the combination of these factors, so even though they are floats, one would expect … [View More]
