![]() ![]() The "Frame Rate FPS" entry adjusts the display frame rate. The zero-G case simulates being in orbit or far away in space with no gravitational forces. The "G Acceleration" entry can be adjusted to have Earth surface acceleration (9.8 m/s 2) or any other value including zero. More detail at this link: Wikipedia: Coefficient of Restitution Each of these dimensions has an independent energy. Remember that there are three dimensions and three particle energies - X (left/right), Y (up/down) and Z (toward/away). ![]() An entry of 0 causes the particle's energy to be entirely lost in the dimension perpendicular to the wall's orientation. An entry of 1 makes the container perfectly elastic, meaning no particle energy is lost during a bounce. When the simulator is restarted, a given particle's velocity is randomly generated to lie between +n and -n using this entry's value, in each of the X, Y and Z dimensions.Īs explained above, the "Energy Restitution" entry adjusts the elasticity of the container's walls. The "Maximum Velocity" entry chooses the highest velocity randomly assigned to each particle. The "Particle Radius" entry chooses the particle size, from tiny to beach-ball size. Larger numbers won't hurt your computer (but maybe your eyes). More than about 50 makes it difficult to figure out what's going on. The "Particle Count" entry selects the number of simulated particles. The container's properties may be adjusted - its walls may be perfectly elastic, losing no energy, or they may lose a specified amount of energy on each bounce, using the "Energy Restitution" entry. This is an experimental computer graphics application that allows you to explore the behavior of particles in a container. ![]()
