What's available?

• Instantiate and run tools from setup files or programmatically 
• Perform batch processing of common workflows (e.g., inverse kinematics, computed muscle control, EMG-driven simulation).
• Utilize the OpenSim API without the overhead of learning to program in C++ and setting up a development environment
• Write "main" programs similar to those written by C++ developers, while taking advantage of the many open-source Matlab/Python packages for data processing, statistics, machine learning, etc. 
• Access a limited subset of Simbody multibody calculations.
• Access to the OpenSim API to create and simulate models 

• Use the Simbody visualizer

Limitations

• In general, cannot create new component (e.g., a custom muscle; though there are some exceptions).
• Cannot create plugins for use through the GUI or command-line.
• Not all Simbody classes are available.
• In this mode, there’s no access to OpenSim's plotter (use Matlab/Python native plotter) or visualizer (use the Simbody visualizer).
• Some internal SimTK classes (that belong to the SimTK namespace and simbody internals) are not available for construction, but the most commonly used classes are available (SimTK::Vec3, Vector, Mat33, State, Inertia).

Interfaces

• Matlab
• Python
• The scripting shell in the OpenSim GUI (which is a Jython interpreter embedded in the application)
• A Jython interpreter
