PyElastica v0.3.3 Release Notes

Major Changes

This release introduces updates, new examples, and minor bug fixes to PyElastica. Several typing improvements have been made across core modules (rods, rigid_body, systems, contact, etc.), which will improve readability, maintainability, and debugging.

In terms of features, a new OperatorGroup system has been added for handling constraints and callbacks, improving modularity. All modules now receive time as an argument, in case a user desires to implement external forcing/couple condition that depends on time.

Example cases have been expanded with cantilever load and unconstrained tumbling simulations, along with a new underhand knot case.

Finally, PyElastica now uses uv as a main dev and deployment scheme.

This version will be the last beta-development version for PyElastica project. Next update will be v1-stable.
