First Release of GravityLab

The first release of GravityLab!
GravityLab is a fast astrophysical N-body simulator written in Python and Cython. Performance-critical parts of the code, such as physics solvers, are implemented in Cython, which makes GravityLab very fast. The main Python module provides a powerful, yet simple class Simulation which makes the process of creating, running, and plotting GralityLab simulations very simple for the user.

This release includes features such as:

• Fast Cython physics solvers

  • N-body integrators:
    • Leapfrog method
    • Euler-Cromer method
  • Acceleration solver
  • Separation solver

• Powerful Python module

  • Simulation class: easily setup simulations
  • Add initial conditions
  • Run simulations
  • Plot positions (with various options)

I wrote this code during my 10th grade, over the summer, as I learned about N-body simulations.
