N Body Simulation Python Packages

msg-nbody

Parallelized direct N-body code in Python + Numba to simulate galaxy mergers with ~2×10⁵ particles

pyvide

A pure-python re-implementation of the VIDE/ZOBOV void finder for simulation boxes, with minimal dependencies and reproducing VIDE bit for bit. It adds tracer weights, non-cubic boxes, per-axis periodicity, a density ceiling and a density-field mode.

gravitylab

A fast astrophysical N-body simulator, written in Python and Cython.

despace

Spatial decomposition without space filling curves

quantum-collider-sandbox

Real-time GPU particle physics simulation with a PDG-accurate catalog of 40 particles. Collisions, decays, and annihilations with relativistic kinematics.
