    DustBall¶. The DustBall component provides the initialization for a set of GSParticles.The following components are required to instantiate an instance: ParticleSystem (describes the number and size of particles in the usual way). GSParticles (indicates to GE2 that these particles will be evolved by a GSController). DustBall (provides an inspector to indicate the size and initial velocity of ...

    Gravity Engine 2 (GE2) provides an engine for modelling gravitational interactions and orbital mechanics. This includes: N-body Newtonian gravitational interactions. orbit specification in a variety of input forms. ... (GE) class. This is a stand-alone (non-Unity component) to allow flexibility in its use. ...

    KEPLER mode (for transfer orbit) for \(t_1 < t < t_2\) KEPLER mode (outer circular orbit) for \(t > t_2\) Why do this, instead or say maneuvers? The patches allow GE to determine where the ship should be for any time \(t\). This means that user code can change the GE time forwards or backwards and GE can update the ship position.

    The Core Code¶. The essential physics of Gravity Engine 2 is done by the GECore (GE) and GEPhysicsCore (GEPC) classes. This section provides an overview of their architecture and usage. In very general terms GECore manages the data and book-keeping and GEPhysicsCore does the physics evolution via numerical integration and/or propagators as well as applying maneuvers as appropriate.
