Announcing the 2013 yt developer workshop!

yt-dev 2013

We are proud to officially announce the upcoming 2013 yt developer workshop. This three day event, to be held on the campus of the University of California, Santa Cruz on March 6th through 8th, will bring together a diverse group of students, researchers, and developers.

Up to this point, yt development has proceeded largely over the internet, leveraging e-mail lists, our online code repository, and IRC to track, discuss, and evaluate changes to the code. Unfortunately, this model makes it difficult to jump in to development as a newcomer. This workshop will not only allow experienced developers to collaborate in person on new features, but will also be a means for new developers to learn what yt is about and begin contributing. The workshop will include several training sessions, constituting a primer in distributed version control, test-driven development, and best practices for scientific programming.

The workshop will also serve as a venue to plan and execute some of the major new features we are planning for the upcoming yt 3.0 release, including full support for outputs of Lagrangian codes like Gadget, Gasoline and AREPO, better support for oct-based codes like ART and RAMSES, initial conditions generation, the new Grid Data Format, a new way of handling units and unit conversion, non-cartesian geometries, and advanced graphical browser widgets inside the iPython notebook.

More information and a registration form for the workshop are available on the workshop website. We have limited funding support for hotels and airfare. Funds will be preferentially distributed to students and the level of individual support will depend on demand.

If you have questions or concerns about the workshop, please feel free to contact the organizers at

On behalf of the organizing committee,

yt extension modules

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


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


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


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


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 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 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 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.
