The minimum requirements to run the OpenSim GUI:
- Operating System:
- Windows: Windows 7, 8, or 10
- Mac: macOS 10.12 or later (not tested with earlier versions of macOS)
- Processor: 800MHz Intel Pentium III or equivalent
- Memory: 2 GB
- Hard disk space: 1 GB
The name OpenSim refers to two distinct entities, the OpenSim API (which consists of C++ libraries of classes used for modeling and simulation of biological structures, and wrappers for other programming languages) and the OpenSim application (GUI) which builds on the OpenSim API.
As of version 4.0, the GUI is distributed for Windows (64-bit only; not 32-bit) and Mac. Although there have been experimental builds of the GUI on Linux there has been no public distribution. Linux users who want to use the GUI have successfully run OpenSim using virtual machines or other environments that simulate Windows on Linux (e.g., VirtualBox and Wine).
The source code for the API (headers, libraries and Doxygen documentation) is available on the downloads page and on GitHub and can be built for both Windows (32-bit and 64-bit as of 3.1), Mac, and Linux. The API is available in Matlab, Python, Java, and C++. To use the API in C++, users will need to write a main program or a plugin or use the various tools provided as command line executables to perform modeling/simulation. See instructions on GitHub.
