The Einstein Toolkit

North American Einstein Toolkit Workshop, July 26th to 30th 2021

We are planning to have an online Einstein Toolkit Workshop at UIUC July 26th to 30th 2021.

Registration is required, but it is also free.

Topics covered include: Writing code for the Einstein Toolkit, Generating and using initial data produced by LORENE, CarpetX, analyzing data produced by the Einstein Toolkit.

Attendees are encouraged to sign up for short presentations.

Please see the school website for details and registration information.

Einstein Toolkit at ICERM Fall 2020, October 15th

The Einstein Toolkit was featured at the virtual ICERM 2020 Fall workshop on Advances in Computational Relativity.

  • The Einstein Toolkit (Erik Schnetter).
  • NRPy+ (Zach Etienne). NRPy+ is an open-source Python code that converts expressions written in Einstein-like notation into highly optimized C/C++ code, using the powerful computer algebra package SymPy as a backend.
  • Writing your own Einstein Toolkit thorns (Steve Brandt). This tutorial will show you how to extend the Einstein Toolkit.

Weekly telecon

Join us at the weekly Einstein Toolkit phone call at 9:00 am US central time on Thursdays.


The Einstein Toolkit is a community-driven software platform of core computational tools to advance and support research in relativistic astrophysics and gravitational physics.
