Summary of the work performed under the Chan-Zuckerberg Foundation Open Source Software for Science Cycle 4 grant awarded to Sympy and performed by Delft University of Technology. We developed new biomechanics capabilities in SymPy and improved code generation performance for large mathematical expressions.

Timo Stienstra successfully defended "BRiM: A Modular Bicycle-Rider Modeling Framework". Timo developed a multibody dynamics modeling tool that makes it much easier to build and change bicycle-rider models. It nicely allows you to modularly construct these models from components yet still have a minimal coordinate formulation of the dynamics that …

The TU Delft Bicycle Lab has been awarded approximately one third of a $350k grant to the SymPy project from the Chan-Zuckerberg Foundation as part of their "Essential Open Source Software for Science" program. SymPy is joining a host of exciting open source software projects in this program. This is …
