ChaNGa (Charon N-body GrAvity) is a computer code designed for simulating gravitational N-body systems. It is particularly used for astrophysical simulations that involve the dynamics of stars, galaxies, and dark matter in the universe. ChaNGa employs a tree code algorithm for calculating gravitational forces, which allows it to efficiently handle large numbers of particles while maintaining high accuracy.
