Here’s a program for simulating flight paths of N charged bodies (rigidly rotating distributions of point charges e.g. charged molecular fragments interacting with individual particles). Used e.g. for estimating angular distributions resulting from coulomb explosion of molecules.
You can download the simulator with git:
git clone https://andersaspegren.dk/git/nbody-coulomb.git
or as a .tar.bz2 or .zip file.
