Brownian Motion or Random Particle Motion in a Fluid

Simulation of a single particle in a box

Simulate random particle motion with varying:

Container Box

L = 10; W = 5; % rectangular container length and width

Particle

x = 0; y = 0; % starting position coordinates

l = 0.1; % movement length

d = 7; % counting numbers, where degrees of freedom = 4*d

N = 5e4; % number of movement steps
