The object in the simulation that is primarily responsible for limiting the simulation speed is also listed in the Sim Settings Menu. The way this maximum simulation speed is calculated can be adjusted via the Tuning Profile and Limit Multiplier settings in the Sim Settings Menu.

By default, the maximum allowed simulation speed is automatically set by Universe Sandbox based on performance.

The simulation's Simulation Speed will affect the size of the time step, and thus both the speed and the accuracy of the N-body simulation.

Gravity affect the Motion of an object, including its Distance, Speed, Orbital Elements, etc.

The Mass of an object will affect its gravitational force.

Related Properties & Settings Properties Universe Sandbox allows the user to switch between different N-body simulation methods (see Models below). Some N-body simulation methods are faster, but less accurate over time, than others.

The type of N-body simulation methods that is used.

The number of objects in the simulation (the ' N' in ' N-body').

The speed at which an N-body simulation can run on a given computer depends on:

The object are moved to their new positions, and then the simulation moves on to the next time step. At each time step, the gravitational force acting on each object is calculated, then used to determine how each object will move during that time step. An N-body simulation takes small steps forward in time and looks at how each object affects every other object in the system. Universe Sandbox simulates this motion using an N-body simulation, also known as N-body integration, a computational method used to numerically solve the N-body problem.

The mathematical model of a group of objects moving under the influence of gravity (for example, stars and planets moving in space) is known as an N-body problem.
