Swiftest

Swiftest is a software package designed to model the long-term dynamics of n-body systems with a dominant central body, like the solar system. Swiftest is a re-write of the Swifter software package that incorporates modern programming techniques and performance improvements.

Installation

For most users, installing swiftest can be done via pip using the command:

pip install swiftest

This will install the swiftest Python package, which can be incorporated into Python projects using import swiftest. It also will install a standalone executable called swiftest, which can execute simulations from the command line, provided that initial conditions and configuration files are available in the path.

Documentation

Please see the Swiftest documentation page for more details, including advanced installation instructions, user guides, API documentation, and examples.
