Build_status CI Documentation Status codecov Downloads DOI Binder Gitter

PyElastica is the python implementation of Elastica: an open-source project for simulating assemblies of slender, one-dimensional structures using Cosserat Rod theory.

Visit www.cosseratrods.org for more information and learn about Elastica and Cosserat rod theory.

How to Start

PyPI version Documentation Status

PyElastica is compatible with Python 3.10 - 3.11.

$ pip install pyelastica

With this you get a minimal version with very little dependencies.

All options:

  • examples: installs dependencies to run example cases, found under the folder examples.
  • docs: packages to build documentation

Options can be combined e.g.

$ pip install "pyelastica[examples,docs]"

For plotting videos, ffmpeg has to be installed:

$ conda install -c conda-forge ffmpeg

Documentation of PyElastica is available here.

If you want to simulate magnetic Cosserat rods interacting with external magnetic environments you can install the derived package using

$ pip install magneto_pyelastica

Details can be found here.

Tutorials

Binder

We have created several Jupyter notebooks and Python scripts to help users get started with PyElastica. The Jupyter notebooks are available on Binder, allowing you to try out some of the tutorials without having to install PyElastica.

We have also included an example script for visualizing PyElastica simulations using POVray. This script is located in the examples folder (examples/Visualization).
