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

𝑛-Body and Extended Body Gravitation for Kerbal Space Program

Vectorized N-body code (Python)

Libraries to analyze numerical simulations (python3)

Py-SPHViewer is a framework for rendering cosmological simulations in Python using the Smoothed Particle Hydrodynamics scheme.

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.

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

A versatile multifluid HD/MHD code that runs on clusters of CPUs or GPUs, with special emphasis on protoplanetary disks.

Differentiable Cosmological Forward Model

Negative Mass N-body Simulation Codes

This is Nbody6++GPU, an N-body star cluster simulation code, maintained by Rainer Spurzem and team.

Python code to interface with halo catalogs and other Abacus N-body data products

A code to compute the non-linear evolution of the cosmological matter density contrast.

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

Python library for ODE integration via Taylor's method and LLVM

ASSIST is a software package for ephemeris-quality integrations of test particles.

Parallel Barnes-Hut Algorithm

Sophisticated astrodynamics and space mission simulator. Calculate n-body trajectories, perform orbital maneuvers, apply various perturbations, generate plots, and more! Minimal dependencies.

Gravity Simulation (Galaxy Birth) in real time, N-Body and 1-Body

This is a modified version of the L-PICOLA code extending the COLA approach for simulating cosmological structure formation to theories that exhibit scale-dependent growth. It can compute matter power-spectra (CDM and total), redshift-space multipole power-spectra P0,P2,P4 and do halofinding on the fly. It can also include the effects of massive…
