Description

Reaction-Diffusion Simulation

Download

Ilya is a small program that simulates a reaction-diffusion model based on the Brusselator reaction scheme.

Function Explorer

Download

This is the original 1999 interactive function explorer called vExplorer. Unzip the files to somewhere convenient and run the executable. This program is currently being updated.

Linear Pathway Simulator

Download

Simple interactive linear pathway simulator. Press the start button and see what happens.

Diffusion Simulator

 Download

A very simple random walk simulator that can compute the mean x and y movements in addition to the Euclidean distance.


 

Ilya is a small program for Windows which simulates a reaction-diffusion model based on the Brusselator reaction scheme. Ilya simulates a 2-dimensional rectangular plane with opposite edges connected so that the plane actually forms a torus. The plane is divided up into many small area elements (one area element per screen pixel). The simulation involves computing the rates of change of two chemical species labeled X and Y as a result of both chemical transformations (Brusselator scheme) and diffusion of X and Y to and from adjacent area elements.

 

 

 


The following images were taken from the another simulation over a period of about 10 minutes and show the sorts of patterns and structures that can self-organise. On a Pentium 133 MHz computer the evolution can be easily tracked in real-time.

Ilya is freely available for educational, private study and research purposes.

 
Function Explorer

Download


Plot arbitrary functions, any parameters appear as sliders allowing a user to explore howthe function depends on the parameter values. The application can also plot the derivatives and elasticities of the function.

 

 

 

Simple Linear Pathway Simulator

Download

A simple interactive linear pathway simulation. Sliders allow a user to control all the parameters of the pathway and can study the response of the pathway time course of steady state.at steady state the flux and concentration control coefficients are also computed.
