This mini package provides a proof-of-concept of N-body simulations of systems that evolve under only gravitational forces.
- Direct summation for force evaluation, which scales as
- 2nd-order symplectic and 4th-order non-symplectic integrator (Runge-Kutta)
- Currently, the standard unit adopted by the code is as follows:
- Mass: Solar Mass
- Time: Day
- Length/Distance: AU
- An example of initial conditions for the Outer Solar System is provided at
./examples/initial_conditions_outer_solar.py. The example is taken from section I.2.4 of Geometric Numerical Integration, Hairer 2006. - For more details, please see the notebook
./Norbit_demo.ipynb
