The OpenSim team at Stanford is excited to announce the release of OpenSim
2.4, a robust and flexible software package for modeling and simulation of
the musculoskeletal system.  This release includes improvements to
functionality, usability, and visualization that will benefit both new users
and experts.  We encourage you to
download<https://simtk.org/project/xml/downloads.xml?group_id=91> the
software and review the full list of new

The software has undergone extensive internal unit and system testing as
well as external beta testing with walking, running, and upper extremity
motion.  In addition, we’ve verified that the results of Computed Muscle
Control now match or exceed the quality of those achieved in OpenSim version

Some of the new features in version 2.4 include faster and more robust tools
for Inverse Dynamics and Inverse Kinematics, new visualization tools,
enhanced access for API users, several usability improvements, and several
features to help verify your simulation results.  OpenSim 2.4 also has tools
to convert old model and setup files to the latest formats.  We have fixed
several bugs and expanded the documentation.  The user’s guide has a chapter
on conducting an induced acceleration analysis, which is a faster
alternative to a perturbation analysis, and a chapter on getting started as
an OpenSim API user.

If you haven’t yet tried OpenSim or you are using an earlier vision, we
encourage you to give 2.4 a spin.  In addition to the OpenSim 2.4 software
download <https://simtk.org/project/xml/downloads.xml?group_id=91>, we've
provided a full list of the software’s new features and bug
general notes on upgrading <https://simtk.org/frs/download.php?file_id=2993>,
and upgrade details for API
