Read and analyze Einstein Toolkit simulations.
Project description
kuibit
kuibit
is a Python library to analyze simulations performed with the Einstein
Toolkit largely inspired by
PostCactus.
kuibit
can read simulation data and represent it with high-level classes. This
page is mainly intended for developers. Documentation for users is available
here.

Installation
kuibit
is available in PyPI. To install it with pip
pip3 install kuibit
If they are not already available, pip
will install all the necessary dependencies.
kuibit
follows
NEP29 and requires
Python >= 3.7.
If you intend to develop kuibit
, see CONTRIBUTING.md and
follow the instruction below.
Development
For development, we use poetry. Poetry simplifies dependency management, building, and publishing the package.
To install kuibit
with poetry, clone this repo, move into the folder, and run:
poetry install -E full
This will download all the needed dependencies in a sandboxed environment (the
-E full
flag is for the optional dependencies). When you want to use
kuibit
, just run poetry shell
from within the kuibit
directory.
This will drop you in a shell in
which you have full access to kuibit
in "development" version, and its
dependencies (including the one needed only for development). Alternatively, you
can activate the virtual environment directly. You can find where the environment
in installed running the command poetry env info --path
in the kuibit
directory.
This is a standard virtual environment, which can be activated with the activate
scripts in the bin
folder. Once you do that, you will be able to use kuibit
for anywhere.
As of version 1.3.0
, we adopt the following philosophy for git
branches:
master
always corresponds to the latest stable version, the one available on PyPI. Hotfixes are applied directly on master, and a new release is tagged.next
is where most of the development occurs. This corresponds to the next version ofkuibit
.next
often experiences rebasing.- Specific features that can be developed on their separate feature branch. This
will be merged into
next
.
The documentation of the development version is served at sbozzolo.github.io/kuibit/dev.
Help!
Users and developers of kuibit
meet in the Telegram
group. If you have any problem or suggestion, that's a
good place where to discuss it. Alternatively, you can also open an issue on
GitHub.
Documentation
kuibit
uses Sphinx to generate the documentation. To produce the documentation
cd docs && make html
Documentation is automatically generated after each commit by GitHub Actions.
We use nbsphinx to translate Jupyter
notebooks to the examples. The extension is required. Note: Jupyter notebooks
have to be un-evaluated. nbsphinx
requires pandoc. If
don't have pandoc
, you should comment out nbsphinx
in docs/conf.py
, or
compiling the documentation will fail.
Videos
Here is a list of videos describing kuibit
and how to use it:
- Tutorial: Post-processing Cactus simulations with Python
- Introduction on kuibit - Einstein Toolkit Seminar, 2021
- Using kuibit
- kuibit - Einstein Toolkit Summer School, 2021
- Tutorial: Post-processing Cactus simulations with Python - Einstein Toolkit Summer School, 2022
The Using
kuibit
series is a great place where to get started with kuibit
.
Tests
kuibit
comes with a suite of unit tests. To run the tests, (in a poetry shell),
poetry run python -m unittest
Tests are automatically run after each commit by GitHub Actions.
If you want to look at the coverage of your tests, run (in a poetry shell)
coverage run -m unittest
coverage html
This will produce a directory with the html files containing the analysis of the coverage of the tests.
What is a kuibit?
A kuibit (also known as kukuipad, meaning harvest pole) is the tool
traditionally used by the Tohono O'odham people to reach the fruit of the
Saguaro cacti during the harvesting season. In the same way, this package is a
tool that you can use to collect the fruit of your Cactus
simulations.
Credits
kuibit
follows the same design and part of the implementation details of
PostCactus
, code developed by Wolfgang Kastaun. This fork completely rewrites
the original code, adding emphasis on documentation, testing, and extensibility.

kuibit
first users, Stamatis Vretinaris and Pedro Espino, for providing
comments to improve the code and the documentation.

. Consider citing these packages too.
Disclaimer
kuibit
is developed as professional tool that can be used for research to be
published in peer-reviewed journals. As such, kuibit
is tested to ensure that
results are scientifically sound. However, we do not guarantee that the entirety
of the software is correct and does what it is intended to do. Hence, users are
strongly recommended to perform their independent validations and to report any
problem.
