April 22, 2013

New issue 554: Document cosmology units https://bitbucket.org/yt_analysis/yt/issue/554/document-cosmology-units Nathan Goldbaum: There should be an overview of yt's capabilities for handling cosmology simulations. In particular, the 'cm' and 'hcm' patterns for comoving units should be documented.

Exporting to radmc3d
by Andrew Myers April 22, 2013

April 22, 2013

Hi Folks, radmc3d <http://www.ita.uni-heidelberg.de/~dullemond/software/radmc-3d/> is a Monte Carlo radiative transfer code that can produce spectra and images for dust continuum and line radiation. I've written some code to save out a yt dataset into the format it uses for its AMR input files. It needs some cleaning up and documentation, but if this is something other people are interested in, I'd be happy to try to add it to yt code base. In principle, this would let any code with a yt … [View More]

Re: [yt-dev] yt Strategy Meeting Tuesday the 23rd: Change of time!
by Matthew Turk April 22, 2013

April 22, 2013

Hi all, A number of people have written to me off list requesting a change, so this will instead be on Tuesday the 23rd at 1PM Eastern. I've created an event on Google Plus on the yt page. I've set it to public, because we don't have everyone in circles yet on there. Here's the event page: https://plus.google.com/events/cr7ro5oulb5unkr3lfe80njo5o0 -Matt On Sat, Apr 13, 2013 at 10:08 AM, Matthew Turk <matthewturk(a)gmail.com> wrote: > Hi all, > > I'd like to call a brief, … [View More]

[yt_analysis/yt] _identify_base_chunk for Octree codes should not pre-allocate a mask (issue #553)
by Matthew Turk April 18, 2013

April 18, 2013

New issue 553: _identify_base_chunk for Octree codes should not pre-allocate a mask https://bitbucket.org/yt_analysis/yt/issue/553/_identify_base_chunk-for-oct… Matthew Turk: The mask for child octs should not be allocated during the course of `_identify_base_chunk` if it can at all be avoided. This is costly. Responsible: MatthewTurk

Make DomainSubsets a subclass of YTSelectionContainer?
by Matthew Turk April 17, 2013

April 17, 2013

Hi all, Today in IRC, Chris and I went back and forth on the particle deposition stuff in advance of the meeting next week. My task right now is to come up with spatial field chunking for Octs in a consistent way; of course I'll write this up into the extant YTEP, which will allow for feedback particularly from ARTIO, ART and RAMSES folks, but as a quick first pass I was wondering what everyone thought of: 1) Unifying DomainSubsets into a single object with subclasses 2) Making that new base … [View More]

[yt_analysis/yt] cut_region doesn't work in 3.0 (issue #552)

New issue 552: cut_region doesn't work in 3.0 https://bitbucket.org/yt_analysis/yt/issue/552/cut_region-doesnt-work-in-30 Nathan Goldbaum: It seems that subselecting on data objects using field cuts hasn't been implemented in 3.0. ``` #!python from yt.mods import * pf = load('DD0000/DD0000') dd = pf.h.all_data() lt = dd.cut_region("grid['Temperature'] < 1e5") lt['CellMassMsun'].sum() ``` ``` #!python traceback Traceback (most recent call last): File "test2.py", line 8, in <… [View More]

[yt_analysis/yt] Ellipsoidal particle IO does not work (issue #551)
by Matthew Turk April 16, 2013

April 16, 2013

New issue 551: Ellipsoidal particle IO does not work https://bitbucket.org/yt_analysis/yt/issue/551/ellipsoidal-particle-io-does… Matthew Turk: This is because of a bug in the ParticleIOHandler that we fall back on when we define a method of ParticleIO (only Enzo) and do not for a 3D data object (only ellipsoid.)

YTEP-0013: First Class Deposited Particle Fields
by Christopher Moody April 15, 2013

April 15, 2013

Hi all, I've issued a PR for YTEP-0013, which tries to promote deposited particle fields to being a first-class field type. This extends the (field_type, field_name) syntax, adds a new concept of the 'deposit' field_type. If you're at all interested in how particles are treated in yt, I'd encourage you to look at the PR and comment! https://bitbucket.org/yt_analysis/ytep/pull-request/15/ytep-0013-first-clas… Thanks! chris
