Universe Sandbox Simulation Editor

Welcome to the Universe Sandbox UBox simulation editor. This editor allows you to edit your ubox simulations, and provides the ability to group bodies and apply changes to the groups as a whole. This is a work in progress, and functionality and precision will be added to the editor periodically, so please check back often to see any new features.

This editor creates a new json element in simulation.json called Groupings, which stores information about each grouping you create. Within each Body object, a GroupingID will associate the body to a grouping. These properties do not seem to conflict with Universe Sandbox, and are used just for association purposes, when reloading into this editor.

Please send any questions, comments, suggestions, or problem reports to simeditorsupport@astroatomicmodel.org
