PyParticles is a particle simulation toolbox entirely written in python

Visit: http://pyparticles.wordpress.com/ Docs: http://simon-r.github.com/PyParticles/index.html

Simulate a particle by particle model with the most popular integrations methods, and it represents the results on a OpenGL or Matplotlib plot.

PyParticle includes the followings integrations methods

1. Euler method
2. Leap Frog method
3. Rung Kutta method
4. Midpoint
5. Stormer Verlet method

As a forces model it includes:

1. Gravity
2. Particle by Particle spring
3. Constant
4. User defined field

PyParticle offers an easy to use class structure with a fully * interchangeable* integrations method or force model, it also implements the possibility to add some boundary model.

In PyParticles a simulation model is entirely described in a config file that should be edited by the user.

The following are the main command of the PyParticles application.

Start the demo simulation: :

pypaticle_app

Start a simulation described in a config file :

pyparticle_app <file_name>

Start the specified demo simulation :

pypaticle_app --demo springs
pypaticle_app --demo solar_system

Write out a model config file :

pyparticle_app -m

Print out the help and version :

pyparticles_app --help
pyparticles_app --version

During the simulation you can toggle the help message by pressing h

Config file Example: :
