[Users] Inclusion of kuibit in the Einstein Toolkit

[Gabriele Bozzola]

Hello,

congratulations to the release team for the new version of the Einstein
Toolkit!

Looking forward, I would like to propose the inclusion of kuibit in the
Einstein Toolkit.

kuibit is a Python package for post-processing simulations. The tool comes
with
several features for analysis and visualization. For some of the most common
operations (e.g., 2D plot of a grid variable, extraction of gravitational
waves, ...),
users can directly obtain the result without writing any code. The number
of such
ready-made scripts grows with every release of kuibit. For everything else,
kuibit
has a large number of features (
https://sbozzolo.github.io/kuibit/features.html)
that can be used in scripts or notebooks.

kuibit is designed to be user-friendly: it has rich documentation (
https://sbozzolo.github.io/kuibit/),
examples ready to be used, and tutorials. kuibit is also designed to be
developer- and
maintainer- friendly: it is thoroughly commented, and it implements several
continuous
integration pipelines to test, document, and publish the package
automatically.
The high quality of kuibit is also recognized by its publication in the
Journal of
Open Source Software (https://joss.theoj.org/papers/10.21105/joss.03099).

kuibit is largely inspired by Wolfgang Kastaun's PyCactus. kuibit shares
the same
overall design with PyCactus, and in some cases, the implementation details
too.
kuibit would not exist without PyCactus.

As far as I know, 5-10 people are actively using kuibit as their main tool
to interface
with the output of simulations. The feedback I got is overwhelmingly
positive:
users that are new to the Einstein Toolkit praise the simplicity of use and
the comfort
of working in Python; experienced users claim that kuibit allows them to
focus on
the science instead of the technical details.

The next release of the Einstein Toolkit is far in the future, so there is
time to incorporate
any feedback/suggestion that the community might have. I will be happy to
work towards
the goal of including kuibit in the Einstein Toolkit.

Best,
