yt-2.2 Release Announcement
@ Cameron Hummels | Friday, Sep 2, 2011 | 2 minute read | Update at Friday, Sep 2, 2011

(Please feel encouraged to forward this message to any other interested parties.)

We are proud to announce the release of yt version 2.2. This release includes several new features, bug fixes, and numerous improvements to the code base and documentation. At the new yt homepage, http://yt-project.org/ , an installation script, a cookbook, documentation and a guide to getting involved can be found. We are particularly proud of the new GUI, entitled “Reason,” which allows real-time exploration of datasets, and which can be used (locally or remotely over SSH) with no dependencies other than a web browser. A basic demonstration of its usage can be found at: http://vimeo.com/groups/ytgallery/videos/28506477 .

yt is a community-developed analysis and visualization toolkit for astrophysical simulation data. yt provides full support for Enzo, Orion, Nyx, and FLASH codes, with preliminary support for the RAMSES, ART, and Maestro codes. It can be used to create many common types of data products such as:

  • Slices
  • Projections
  • Profiles
  • Arbitrary Data Selection
  • Cosmological Analysis
  • Halo finding
  • Parallel AMR Volume Rendering
  • Gravitationally Bound Objects Analysis

There are a few major additions since yt-2.1 (Released April 8, 2011), including:

  • New web GUI “Reason,” designed for efficient remote usage over SSH tunnels
  • Command-line submission to the yt Hub (http://hub.yt-project.org/)
  • Absorption line spectrum generator for cosmological simulations
  • Support for the Nyx code
  • An order of magnitude speed improvement in the RAMSES support
  • Experimental interoperability with ParaView
  • Quad-tree projections, speeding up the process of projecting by up to an order of magnitude and providing better load balancing
  • “mapserver” for in-browser, Google Maps-style slice and projection visualization
  • Many bug fixes and performance improvements

With this release, we also unveil the yt Hub, an astrophysical simulation-specific location for sharing scripts, analysis and visualization tools, documents and repositories used to generated publications. The yt Hub has been designed to allow programmatic access from the command line, and we encourage you to browse the current offerings and contribute your own. The yt Hub can be found at http://hub.yt-project.org/ .

yt extension modules

yt has many extension packages to help you in your scientific workflow! Check these out, or create your own.

ytini

ytini is set of tools and tutorials for using yt as a tool inside the 3D visual effects software Houdini or a data pre-processor externally to Houdini.

Trident

Trident is a full-featured tool that projects arbitrary sightlines through astrophysical hydrodynamics simulations for generating mock spectral observations of the IGM and CGM.

pyXSIM

pyXSIM is a Python package for simulating X-ray observations from astrophysical sources.

ytree

Analyze merger tree data from multiple sources. It’s yt for merger trees!

yt_idv

yt_idv is a package for interactive volume rendering with yt! It provides interactive visualization using OpenGL for datasets loaded in yt. It is written to provide both scripting and interactive access.

widgyts

widgyts is a jupyter widgets extension for yt, backed by rust/webassembly to allow for browser-based, interactive exploration of data from yt.

yt_astro_analysis

yt_astro_analysis is the yt extension package for astrophysical analysis.

Make your own!!

Finally, check out our development docs on writing your own yt extensions!

Contributing to the Blog

Are you interested in contributing to the yt blog?

Check out our post on contributing to the blog for a guide!

We welcome contributions from all members of the yt community. Feel free to reach out if you need any help.

the yt data hub

The yt hub at https://girder.hub.yt/ has a ton of resources to check out, whether you have yt installed or not.

The collections host all sorts of data that can be loaded with yt. Some have been used in publications, and others are used as sample frontend data for yt. Maybe there’s data from your simulation software?

The rafts host the yt quickstart notebooks, where you can interact with yt in the browser, without needing to install it locally. Check out some of the other rafts too, like the widgyts release notebooks – a demo of the widgyts yt extension pacakge; or the notebooks from the CCA workshop – a user’s workshop on using yt.
