OpenSim

Description

"OpenSim is a freely available, user extensible software system that lets users develop models of musculoskeletal structures and create dynamic simulations of movement." OpenSim includes Python and Matlab APIs. It is commonly used with OpenSim Moco.

The OpenSim module available through our software stack includes support for OpenSim Moco, as well as bindings to enable scripting in Python or Matlab.

Using OpenSim via Matlab

Setup

Matlab Setup for First Use

Before first use of OpenSim on a cluster, you must configure the necessary Java paths by running the following command:

matlab -batch "cd ${EBROOTOPENSIM}/share/doc/OpenSim/Code/Matlab/; configureOpenSim"

After exiting and relaunching Matlab, you can verify that OpenSim is imported by running the following in Matlab: org.opensim.modeling.opensimCommon.GetVersion()

Using OpenSim via Python

In order to use the OpenSim Python package, an OpenSim module must be loaded, and a numpy package must be available through a virtual environment or loading a scipy-stack module. You should subsequently be able to import the opensim package in Python.
