Update on github migration
by Nathan Goldbaum April 11, 2017

April 11, 2017

Hi all, Thanks to efforts from Kacper, Matt, and myself we now have a working github mirror: https://github.com/yt-project/yt-test This repo is available purely for testing purposes. It should always be in sync with the latest changes in the bitbucket repository. There is a chance that we will need to redo the conversion and change all the hashes so don't rely on this repo being here forever. In addition, Kacper has verified that our Jenkins test suite works more or less out of the box on a … [View More]

Issue #1344: Metallicity is broken in the stream frontend for grid data (yt_analysis/yt)
by John ZuHone April 8, 2017

April 8, 2017

New issue 1344: Metallicity is broken in the stream frontend for grid data https://bitbucket.org/yt_analysis/yt/issues/1344/metallicity-is-broken-in-t… John ZuHone: If one sets up a stream dataset with metallicity as an input field, the values get transformed. A simple script demonstrates this: ```python import numpy as np import yt Z = np.random.uniform(size=(32,32,32)) d = np.random.uniform(size=(32,32,32)) data = {"density": d, "metallicity": Z} ds = yt.load_uniform_grid(data, (32,32,… [View More]

migration ytep
by Matthew Turk April 5, 2017

April 5, 2017

Hi folks, Here's a draft YTEP about migration: https://bitbucket.org/yt_analysis/ytep/pull-requests/68/adding-draft-github… I'll update with comments soon, once a sample conversion has been made and put on the GH page. Comments are welcome, but right now, it'd be much more useful if they were along the lines of "here's something that also will need to be done" since this is in its early phases. But, it's also probably true that we can start moving forward with phase 1 toward phase 2 already. -Matt

New default particle union?
by Nathan Goldbaum April 3, 2017

April 3, 2017

Hi all, I'd like to propose adding a new particle union that should be defined for all datasets that include particles. This came up in the context of the demeshening work (see https://bitbucket.org/yt_analysis/ytep/pull-requests/67 for more details). Right now many of the derived quantities make a distinction between calculating results using just the gas or just the particles or both. Up until now they have calculated the results for particles using particle fields from the 'all' particle … [View More]
