Scripting Environments

OpenSim's scripting capabilities allows users to:
  • 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
  • Access a limited subset of Simbody multibody calculations.

However, not all of OpenSim's functionality is available through scripting. Specifically:

  • 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.


You can access OpenSim scripting through
  1. Matlab
  2. Python
  3. The scripting shell in the OpenSim GUI (which is a Jython interpreter embedded in the application)
  4. A Jython interpreter. 
The sections below outline how to get started with scripting and describe the available functionality.
