SymPy 1.13 and Opty 1.3 can now be used for optimal control solutions of muscle-driven biomechanical simulation. This blog post shows of a solution to a muscle driven cycling time trial.

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.

Dr. Leila Alizadehsaravi and Dr. Felix Dauer are featured in the final CAS project video with the balance assist bicycle.

Yesterday, we posted a new preprint to engrXiv: J. K. Moore, B. Cloud, M. Hubbard, and C. A. Brown, "Analysis and Ethical Design of Terrain Park Jumps for Snow Sports," Preprint, Mar. 2021. [Online]. Available: https://doi.org/10.31224/osf.io/sq7u9. The abstract reads: Most American snowsport resorts …
