%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.
