When turned off, objects will not experience Roche fragmentation.When turned off, objects involved in collisions will not fragment.Toggling off Create Fragments will turn off all of the following settings. When this setting is turned on, the simulation will automatically pause at the point when the next object collision occurs.įragment Creation Create Fragments If this setting is turned off, collisions will not heat objects. If this setting is turned off, objects will pass through one another rather than colliding. If the Auto Limit Simulation Speed setting is off, this setting will display None, as there will be no performance limit on the Simulation Speed. This setting is read-only and is automatically calculated by Universe Sandbox. This is often the object with the smallest orbit. This setting displays which object in the simulation is currently the source of the maximum orbital error, and therefore the object responsible for limiting the maximum Simulation Speed. The maximum allowed Simulation Speed is automatically limited based on the orbital error in the simulation.

The Accuracy profile has a Limit Multiplier of 0.1, and the Performance profile has a Limit Multiplier of 10.ĭisplays the current number of substeps calculated within each time step. For example, when Limit Multiplier is set to 2, the maxmimum allowed Simulation Speed will be twice the size of the allowed Simulation Speed of the Balanced Profile. The value of this setting will scale the allowed maximum Simulation Speed relative to the Simulation Speed of the Balanced tuning profile.

A read-only value that shows the reduction in calculation that the gravity tree method requires, compared to the previous method.Ĭhanges the type of N-body integrator used to simulate gravity.

A higher ratio may allow a faster computation, but could also produce more inaccuracy.

Represents the resolution of the gravity tree algorithm.

The gravity tree uses the following settings: When this setting is off, the user can set the Simulation Speed to any value, potentially reducing the accuracy of the simulation enough to prevent any realistic orbits.Įnables an experimental gravity calculation method, which greatly improves performance in simulations with a large number of objects, but may decrease performance in simulations with a small number of objects.

When this setting is on, Universe Sandbox will automatically limit the maximum possible Simulation Speed of a simulation to maintain a certain level of accuracy. Gravity Simulation Accuracy Auto Limit Simulation Speed This is the same setting controlled by the Gravity button in the Sim menu in the bottom bar.Įnables gravity for other simulation features that depend on gravity, such as: volatile evaporation, spin fragmentation, and surface phase changes. Gravity Enable Gravity Gravitational Constant Ĭontrols the strength of the Gravitational Constant.ĭetermines whether objects will be able to attract each other gravitationally in the N-body simulation. Allows the user to change the Time Zone of the date and time display.ĭisplays the Average Simulation Speed of the simulation.Ĭontrols the Target Simulation Speed of the simulation.
