💫 An open-source multi-purpose N-body code.

𝑛-Body and Extended Body Gravitation for Kerbal Space Program

Implementations in Unity of the Ten Minute Physics YouTube channel. Instead of using Unity's built-in physics engine, you will learn how to make your own. This is useful if you want to simulate ropes, cloth, tires, etc. You will also learn how to make fluid simulations and soft body physics.

C++ library for ODE integration via Taylor's method and LLVM

A simulator of gravitationally bound systems.

Vectorized N-body code (Python)

Software rasterization, N-Body simulation and Game of Life in Rust + Haskell

SPH-EXA is a C++20 simulation code for performing hydrodynamics simulations (with gravity and other physics), parallelized with MPI, OpenMP, CUDA, and HIP.
