OpenSim: An Open Source Biomechanics Simulator to Study Movement

Project OpenSim
Funding Cycle 2

Proposal Summary

To improve the usability, computational performance, maintenance and outreach of the open source software OpenSim and to support the education and training of its users around the world.



OpenSim is an opensource biomechanical simulator that models the mechanics of articulating bones and contractile muscles to generate physics-based simulations of movement. OpenSim has a growing community of biomechanists, rehabilitation roboticists, comparative biologists, neuroscientists and computer scientists, now totaling over 12,000 users.
