SymPy Biomechanics

[Jason K. Moore]

Hi,

As part of a Chan-Zuckerberg Initiative EOSS grant, we developed a new SymPy Biomechanics package within SymPy.

We have an introductory tutorial and explanation: https://docs.sympy.org/dev/tutorials...mechanics.html

and an example model and simulation: https://docs.sympy.org/dev/tutorials...l-example.html

The documentation for the API is here: https://docs.sympy.org/dev/modules/p...ics/index.html

This package will be included in the SymPy 1.13 release later this year, but you can try it out with the development version of SymPy now.

We also have a blog post detailing all the work done in the grant, including demonstrations of solving trajectory optimization problems with opty and pycollo from SymPy mechanics/biomechanics models: https://mechmotum.github.io/blog/czi-sympy-wrapup.html

Feedback can be given here or on the SymPy communication channels (email list, github discussions, github issues). We'd love for people to give it a go and we are also very welcoming to contributions.

SymPy 1.13 was finally released this summer, so you can now use SymPy Biomechanics by installing it from PyPi or Conda Forge. We have also released Opty 1.3, which solves optimal control problems using SymPy and have a new example demonstrating an optimal control solution of a SymPy Biomechanics model: https://opty.readthedocs.io/stable/e...ime_trial.html. Feedback is welcome on the projects' mailing lists or Github.
