Abstract

The following simulations are a variety of abstract systems that can be studied, modified, and used as a source of ideas for further investigation.

Collapsing Cloud simulates a cloud of 100 identical particles that are initially stationary.
Globular Cluster Collision simulates two globular clusters on a collision course, each containing 401 identical stars.
Globular Cluster simulates a globular cluster of 401 identical stars.
Many Body System simulates many massive stars orbiting a much more massive 'core' star.
Projectile simulates the Earth together with a single projectile.
Protoplanets 2D - 1 simulates a central star together with 400 identical protoplanets.
Protoplanets 2D - 2 simulates a central star together with 400 identical protoplanets.
Protoplanets 3D - 1 simulates a central star together with 400 identical protoplanets.
Protoplanets 3D - 2 simulates a central star together with 400 identical protoplanets.
Spiral Arms simulates a galaxy in which the core is represented by a single large particle, the rest of the galaxy is represented by a disc of 1,000 stars, and a second galaxy is represented by a single massive particle.
Three Body System simulates three similar particles, with two particles orbiting each other in a close circular orbit, and as a pair orbiting a third particle in a much larger and eccentric orbit.
Two Body System simulates the simplest simulation of interest - a two body system with one body orbiting the other in an eccentric orbit.

The descriptions of the more complex systems include details of how they were created, which can modified to create similar systems.
