%description
This project is a SimTK tool set providing general multi-body dynamics
capability, that is, the ability to solve Newton's 2nd law F=ma in any set
of generalized coordinates subject to arbitrary constraints.  Simbody is
provided as an open source, object-oriented C++ API and delivers
high-performance, accuracy-controlled science/engineering-quality results.

Simbody uses an advanced Featherstone-style formulation of rigid body
mechanics to provide results in Order(n) time for any set of n generalized
coordinates. This can be used for internal coordinate modeling of molecules,
or for coarse-grained models based on larger chunks. It is also useful for
large-scale mechanical models, such as neuro-muscular models of human gait,
robotics, avatars, and animation. Simbody can also be used in real time
interactive applications for bio-simulation as well as for virtual worlds and
games.
