SMN Particle Simulator v3.2

This version has been superceded by: SMN v5.1 ParticleDraw

SMN Particle Simulator is an SMN based simulation context for arbitrary systems of particles. This will later be extended to arbitrary systems, not just particles.

This version implements more of the functionality of SMN, such as the use of sparse matrices and energy flow processing.

This is a DOS based program and it should run on all windows systems (linux versions coming soon).

Download Software (226 Kb, Dos/Windows), just unzip and run “particle.bat”. Note: this version will be updated regularly until it reaches a steady state (this version uploaded on 2006/02/06) Note: any p32 files made with previous versions will need to be re-computed and saved again.

More information on the SMN system modeling paradigm. In particular the SMN high level design.

There are also other programs.

In v3.2b there are many small changes but the main difference is...
There are two ways to represent a system matrix and two ways to process one. v3.1 only illustrated the simplest, most brute force approach whereas v3.2 illustrates both representation methods and both processing methods. See the sub heading "Changing Computational Method:" in the section on "Model Parameters:", in ReadMe.txt, or refer to the related discussion in Finite Discrete Information Systems.

In v3.1 the interface was enhanced to provide more flexible interaction with the system model to allow one to edit many of the simulation parameters and load or construct new system models.

Note: the simulation is not meant to be physically realistic to the n'th degree, this is just a simple illustration of some of the capacities of the SMN modeling paradigm.

Screen Shots of v3.1, they are visually very similar.

Click on the images below to see the full size image.

A simple system model consisting of three hard or fermionic particles (repel at close range) that are locked into a triatomic molecular bond, and showing the options available for interacting with the system model.

A new system has been loaded from file and their radii are being increased.

The particles have settled into a new equilibrium state and now the central particle is being given a velocity using the billiards method.

The same model after the screen sizes of the particles have been changed and the central particle is being changed again.

A new system of 18 soft or bosonic particles (attract at close range) and showing the general menu.
