GravityLab 2.1

Fast astrophysical N-body simulator

GravityLab: Astrophysical N-body simulator.

An astrophysical N-body simulator.

Installation

Dependencies

The following are required to run GravityLab:

• Cython
• NumPy
• Matplotlib

Install

To install this code, run the following commands in your terminal:

> git clone https://github.com/Kushaalkumar-pothula/gravitylab.git
> python setup.py build_ext --inplace

Usage

You can run the simulation using the gravitylab.simulate module. This module provides a simple yet powerful class Simulation. A Simulation instance can be instantiated with the following command (Simulation parameters not shown here):

from gravitylab.simulate import Simulation
my_simulation = Simulation()

Add initial conditions to a simulation instance:

my_simulation.initial_conditions()

And then run a simulation using the .run() method:

positions = my_simulation.run()

The positions variable is a N x 3 array of positions which can be plotted.

An example for running GravityLab simulations can be found in gravitylab/example.py:

> python gravitylab/example.py
