The nMod nBody Modelling Toolkit

The nMod nBody Modelling Toolkit provides software to run experiments in the field of nBody modelling on a normal home computer.

This means modelling asteroid/comet motion, spacecraft flight, planetary systems, or stellar cluster/small galaxy systems.

The toolkit contains a Particle Particle nBody model, an OpenGL viewer to display the output of the nBody model, and a number of utilities for generating new projects and editing existing output files.

For tutorials on these tools and nBody modelling in general, read the user manual.

The announcements page is where I report bug fixes, as well as news regarding the nMod Toolkit, so it's a good idea to visit this each time you come to the site.

Operating systems currently supported are Linux and Windows XP. The current stable nMod Toolkit version is 3.1d

nMod comes with a default project which represents the solar system as it was on the 24th of august 2006. I have included Point Mass representations of the Spacecraft Voyager 1 and 2, and Pioneer 10 and 11. They are as close to their real positions as I can get them, and should closely approximate their real trajectories when the system is iterated.

Reference Builds are provided for the nbody model and the viewer. These can be used for simple experiments. More advanced work (such as using evolutionary algorithms to discover an optimal orbit for a spacecraft) will require the creation of a separate application. The reference builds should be a good starting place for such work.

nMod-ea is available now. This is an enhanced version of the nMod Toolkit specially designed for evolutionary algorithm based research. The next reference release will be built on this new version.
