@ Sam Skillman | Friday, Apr 8, 2011 | 1 minute read | Update at Friday, Apr 8, 2011

We are proud to announce the release of yt version 2.1. This release includes several new features, bug fixes, and numerous improvements to the code base and documentation. At the yt homepage, http://yt.enzotools.org/ , an installation script, a cookbook, documentation and a guide to getting involved can be found.

yt is an analysis and visualization toolkit for Adaptive Mesh Refinement data. yt provides full support for Enzo, Orion, and FLASH codes, with preliminary support for RAMSES, ART, Chombo, CASTRO 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-2.0 (Released January 17, 2011), including:

  • Streamlines for visualization and querying
  • A treecode implementation to calculate binding energy
  • Healpix / all-sky parallel volume rendering
  • A development bootstrap script, for getting going with modifying and contributing
  • CASTRO particles
  • Time series analysis

$ bash install_script.sh

Development has been sponsored by the NSF, DOE, and University funding. We invite you to get involved with developing and using yt!

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!

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.
