Hey all, Anybody want to write a blog post or two for the blog? I think having just short little ones about some new things in yt would be great. Like, a short one talking about new things in 3.0 for instance. Anybody interested? -Matt

New issue 908: data_source.volume() still uses 2.x CellVolume field https://bitbucket.org/yt_analysis/yt/issue/908/data_sourcevolume-still-uses… John Wise: The `volume()` call in the `YTSelectionContainer3D` object still uses `CellVolume` to calculate the volume.

GDF PR--call for some feedback
by John Zuhone Sept. 22, 2014

Sept. 22, 2014

Hi all, I have a work-in-progress PR in the hopper regarding GDF reading and writing: https://bitbucket.org/yt_analysis/yt/pull-request/1001/wip-some-gdf-writing… What it does is implement direct writing of covering grids to GDF files (something I've been using in my research, to work with the resulting files directly in yt) and clobbering existing files with the same path if the user allows for it. However, when fiddling around with this I determined that it was necessary to make GDF more … [View More]

soliciting for help with a possible Boston-based yt workshop
by John ZuHone Sept. 19, 2014

Sept. 19, 2014

Hi developers, Well, I was only here in Cambridge for two weeks and someone already asked me if we could do a local yt workshop for users. They suggested that between CfA, MIT, and the other various institutions that there is probably a critical mass for a small workshop. I would be happy to organize and lead such a workshop, but it would be a lot easier on me if I had one or two others to help assist. This would be a small endeavor, and only local, but I was wondering if any of you might … [View More]

Issue #907: changing units manually in FLASH datasets (yt_analysis/yt)
by Salvatore Cielo Sept. 19, 2014

Sept. 19, 2014

New issue 907: changing units manually in FLASH datasets https://bitbucket.org/yt_analysis/yt/issue/907/changing-units-manually-in-f… Salvatore Cielo: Hello everyone, I am a new yt user; working with FLASH datafiles. FLASH files work smoothly in general, but the front-end seems to lack the possibility to change the unit system in reading, on the contrary of some other dataset (e.g. Athena) where one can specify units at load time. I need to specify a custom unit system; either at load time … [View More]

Sept. 19, 2014

New issue 906: Active Particle FieldNotFound https://bitbucket.org/yt_analysis/yt/issue/906/active-particle-fieldnotfound John Regan: I've added an ActiveParticle to Enzo which is created at a user appointed time. Running YT on the output before the particle is created causes YT to exit with the error yt.utilities.exceptions.YTFieldNotFound: Could not find field '('RadiationParticle', 'particle_velocity_z')'. Tunning YT on the outputs after the particle is created presents to problems. The … [View More]

Issue #904: Reading in orion sink / star particle files is busted in yt-3.0 (yt_analysis/yt)
by Andrew Myers Sept. 19, 2014

Sept. 19, 2014

New issue 904: Reading in orion sink / star particle files is busted in yt-3.0 https://bitbucket.org/yt_analysis/yt/issue/904/reading-in-orion-sink-star-p… Andrew Myers: This was reported via email by Stella Offner and Brandt Gaches. The code that reads them in needs to be updated to handle units. Also, the detection of particle fields got busted in some of the refactoring that went along with the transition from 2.X to 3.0.
