Elastica is a software to simulate the dynamics of filaments that, at every cross-section, can undergo all six possible modes of deformation, allowing the filament to bend, twist, stretch and shear, while interacting with complex environments via muscular activity, surface contact, friction and hydrodynamics.

Installation

PyPI version

PyElastica is compatible with Python 3.6 - 3.8. The easiest way to install PyElastica is with PIP.

$ pip install pyelastica

Documentation of PyElastica is available 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).
