Several pre-configured simulations come built into Spring Chain
and are accessible by choosing them from the Simulations pull-down menu.
These simulations automatically customize themselves to fit into the scale
and parameters that you have chosen. For instance, no matter how many particles
you are monitoring, choosing the ‘Sine’ simulation will always give one
full period of a sine wave. It should be noted, however, that if you change
the number of particles after choosing a simulation, you must reselect
that simulation from the pull down menu to have the particle positions
A description of each of the simulations is given below:
- Random- this simulation assigns each particle a random position
and velocity according to the current scale of the animation graph.
- Sine- this simulation places the particles in the position of
one full period of a sine wave and sets all the initial velocities to zero.
- Gaussian- this simulation alligns the particles in a pulse configuration
resembling a Gaussian distribution.
- Modulated Gaussian- this simulation orients the particles in
the configuration of a sine curve multiplied by the Gaussian distribution.
- Symmetric Mode- a well studied configuration in many mechanics
class, in this simulation the particles are aligned in a configuration
that is symmetric on either side of the center of the chain.
- Antisymmetric Mode- another well studied configuration, in this
simulation the particles are aligned in a configuration that shows one
half of the spring chain to be the exact opposite of the other.
- Pulse- this simulation places the particles in an orientation
resembling a single pulse of a square wave.
- Symmetric Pulse- this simulation places the particles into two
square wave pulses—one positive and one negative.
