| License | The GUI and API are open source under Apache 2.0, while models, examples, and plugins may have their own licenses. | The repository identifies its license as GPL-3.0. |
| Purpose | OpenSim models humans, animals, robots, and the environment, and simulates their interaction and movement. | RustBCA is a general-purpose code for simulating ion–material interactions, including sputtering, reflection, and implantation, using the binary collision approximation. |

In their own words
OpenSim
OpenSim models and simulates how humans, animals, robots, and their environment move and interact. Its graphical interface displays models and supports creating and analyzing simulations. Models can contain rigid bodies, joints, constraints, contact, muscles, and other actuators. Movement analysis tools include inverse kinematics, inverse dynamics, static optimization, and forward dynamics; Computed Muscle Control can generate muscle-driven forward simulations. The API is usable through Matlab, Python, Java, and C++, and GUI scripting uses an embedded Jython shell. Plugins can add analyses and model components, but must be built for the same OpenSim version and platform. The graphical interface is distributed for 64-bit Windows and Mac, while there is no public Linux GUI distribution; the API source can be built for Linux. OpenSim is free and open source under Apache 2.0, though models, examples, and plugins may have separate licenses. It is intended for research and teaching and welcomes academic and commercial applications. Documentation, tutorials, and a discussion forum are available. Downloading requires a SimTK account.
