OpenSim 3.3

Design and customize the musculoskeletal structures for 3D models. Work with presets or build a new layout from scratch, then launch a testing simulation to observe the behavior of a model in real time. Adjust the skeletal parameters to optimize the results.

OpenSim is a freely available, user extensible software system that lets users develop models of musculoskeletal structures and create dynamic simulations of movement.
OpenSim technology makes it possible to develop customized controllers, analyses, contact models, and muscle models.
