Description: OpenSim is a freely available, user extensible software system that lets users develop models of musculoskeletal structures and create dynamic simulations of movement.
Simtk.org is the home of the software framework initiated and developed by Simbios, the National NIH Center for Biomedical Computing focusing on Physics-based Simulation of Biological Structures. Simtk.org represents a centralized organization, a place, where like-minded people can gather to collectively pursue their interests in research areas, related to physics-based simulation of biological structures. One important goal is for Simtk.org to serve as a repository for models that are published (as well as the associated code) to create a “living” archive of simulation scholarship. Hence, anyone interested in physics-based simulation in biomedicine can come to the site and find the right project.
