A library for including additional forces in REBOUND
Project description
A library of additional effects/forces for REBOUND simulations
FEATURES
REBOUNDx allows you to easily add typically used modifications to your REBOUND simulations. So far we include:
Post-newtonian general relativity corrections
Semimajor axis and eccentricity damping, implemented as forces
Direct modifications to particles’ orbital elements after each timestep
Installation
You’ll have to have git installed. In a terminal, navigate to the location where you want to put the reboundx folder. Then:
git clone https://github.com/dtamayo/reboundx.git
REBOUNDx also needs to know where REBOUND is installed on your machine. You tell it by setting the REB_DIR environment variable. One good way to do this is to edit your .profile:
cd ~ pico .profile
and add the line:
export REB_DIR=/Users/dtamayo/rebound
where you would replace the path to your own installation. Now close your terminal, open a new one and you’re all set!
Examples
You can find working examples in reboundx/examples. The gr example adds post-newtonian corrections. The modify_orbits example shows how to add semimajor axis / eccentricity damping to simulations, either through direct modifications of the orbital elements, or through forces.
