System Setup

Create a simulation and add bodies

Run the N-body simulation

Re-center, measure, check, and continue a run

shift_reference_frame(): Shift the coordinate reference frame of the simulation
get_orbital_elements(): Osculating orbital elements of a body relative to a parent
get_energy(): Total energy of a simulated system
get_momentum() get_angular_momentum(): Total linear and angular momentum of a simulated system
conserved_quantities(): Conserved quantities and how well a simulation conserved them
continue_simulation(): Continue a simulation from its last state
system_from_simulation(): Rebuild an orbit_system from a simulation snapshot

Plot and animate results

plot_orbits(): Plot Orbital Trajectories (Smart 2D/3D Dispatch)
plot_orbits_3d(): Plot 3D Interactive Orbital Trajectories
plot_system(): Plot System Snapshot at a Single Time (Smart 2D/3D Dispatch)
plot_system_3d(): Plot 3D Interactive System Snapshot at a Single Time
animate_system(): Animate the System Over Time (Smart 2D/3D Dispatch)
animate_system_3d(): Animate the System Over Time in Interactive 3D
