OpenSim is a freely available software project for musculoskeletal modeling and dynamic simulation. The community uses OpenSim to uncover the biomechanical causes of movement abnormalities and to design improved treatments. Individuals around the world contribute models, scripts, data, and plugins to enhance the software.
