Issue #819: Octree is not a true depth first traversal (yt_analysis/yt)

New issue 819: Octree is not a true depth first traversal https://bitbucket.org/yt_analysis/yt/issue/819/octree-is-not-a-true-depth-f… Anonymous: In order to make yt's octree compatible with Hyperion (and other codes: Sunrise, Turtlebeach), it would be best created in a true depth first manner, rather than pseudo-depth first as it currently is. i.e. http://docs.hyperion-rt.org/en/stable/advanced/indepth_oct.html#indepth-oct Responsible: MatthewTurk

Issue #815: Tipsy: Plots fail if index, etc. aren't called first (yt_analysis/yt)
by Ben Keller March 26, 2014

March 26, 2014

New issue 815: Tipsy: Plots fail if index, etc. aren't called first https://bitbucket.org/yt_analysis/yt/issue/815/tipsy-plots-fail-if-index-et… Ben Keller: SlicePlot and ProjectionPlot will fail unless the smoothed fields are setup (I think?). So if field_list or index, etc. are called before the plot routine. If they aren't the plot fails with an indexError thrown. I think this should be a quick fix...

Issue #814: NMSU-ART periodicity (yt_analysis/yt)
by karraki March 25, 2014

March 25, 2014

New issue 814: NMSU-ART periodicity https://bitbucket.org/yt_analysis/yt/issue/814/nmsu-art-periodicity karraki: NMSU-ART may have some periodicity issues. Found by examining the number of particles returned after some operation versus the total number of particles in the data set. This occurs within io.py in the read_particle_selection definition comparing the mask and arr sizes. One particle gets masked out. For dd['specie3','particle_mass'].size it should be 2093021 but returns 2093020. … [View More]

New issue 813: Mass units https://bitbucket.org/yt_analysis/yt/issue/813/mass-units Andrew Elvin: Reads in Bolshoi Planck particle data and prints out maximum value for field ('deposit', 'all_mass'). Value output is on the order of Msun/h and units assigned are grams. current version: 2052f06e3786 Responsible: MatthewTurk

Importing yt versus importing yt.mods
by Matthew Turk March 25, 2014

March 25, 2014

Hi all, Some of this was hashed out before on the YTEP-0019 discussion, but I am going through and re-implementing some of that now and I wanted to bring it back to the group. What we had come up with was: * import yt => gets most of the items used in yt in the main namespace * import yt.mods => treats yt more like an application, gets everything but *also* does "startup tasks" Now, the big benefit to making it like this is that you can do: import yt and get everything. The *… [View More]

Old halo objects
by Matthew Turk March 24, 2014

March 24, 2014

Hi all, With the new halo analysis machinery that Britton, Brian C and Hilary have been working on getting integrated into mainline, do we still need the old halo objects machinery? It seems to me that if we are able to replicate all the functionality, *and* call the old halo finders, we don't need the actual code for "class Halo" and "class HaloFinder" and the like. This is the stuff that's mostly in halo_objects.py in yt/analysis_modules/halo_finding/ . Britton, Brian and Hilary -- does … [View More]
