Diffusion Limited Agregation


One or several particles are randomly generated in the circumference, and they take random gaussian walks (their lengths  are also randomly produced) in each step the direction (up, down, right or left) is selected at random.  If a particle hits one of the fixed particles inside the circle it sticks. When the walk end and the particle does not hit another one, it disappears and new ones are produced. The particles  that go out the circle are eliminated.
This model is used to simulated dendrite formation, electrolitic deposition and other phenomena.

Instructions

Start: Begins the simulation
Pause: Makes a pause in the simulation
Stop: Stops the simulation
Reset:Erases the particles inside the circle.
Num +: Increases the number of particles generated on the circumference
Num -: Decreases the number of particles generated on the circumference
The number of generated particles is in the box
 
To select several "seed" particles, click inside the circle.
