rebound in the problem directory to run them No configuration is needed to run any of the example problems.All features are inluced in the public repository on github No dependencies on external libraries (use of OpenGL/glfw3 for visualization is optional).Parallelized with MPI is supported for some special use cases only (using an essential tree for gravity and collisions).Parallelized with OpenMP (for shared memory systems).Real-time, 3D OpenGL visualization (C version).Extensive set of example problems in both C and Python.Easy-to-use Python module, installation in 3 words: pip install rebound.The code is written entirely in C, conforms to the ISO standard C99 and can be used as a thread-safe shared library.Support for collisional/granular dynamics, various collision detection routines.High accuracy non-symplectic integrator with adaptive time-stepping (IAS15).Hybrid symplectic integrators for planetary dynamics with close encounters (MERCURIUS).High order symplectic integrators for integrating planetary systems (SABA, WH Kernel methods).Symplectic integrators (WHFast, SEI, LEAPFROG, EOS).REBOUND is very flexible and can be customized to accurately and efficiently solve many problems in astrophysics. The particles can represent stars, planets, moons, ring or dust particles. a software package that can integrate the motion of particles under the influence of gravity.
