phantom-geodesic

geodesic integrator for relativistic orbits

Mainly used as a test code for the PHANTOM General Relativistic Smoothed Particle Hydrodynamics code, but functional as a standalone geodesic integrator

Usage

make
./grtest

Requirements

• gfortran compiler

Options

Can change metric, setup or whether or not to use Newtonian gravity, e.g.

make NEWTONIAN=yes

And yes, compile-time options are a bit annoying. This would be nice to fix.
