Next simulations attempt to recreate dune formations by using the computational logic behind the Cellular Automata: Abelian Sand-Pile Model rule set. Adjustable variables are put in place to control various parameters of the simulation and to visualize the different outcomes they create. Dune Frequency adjusts the size of the dunes formulating in X,Y,Z directions. Surface Amplitude generates the initial X,Y,Z conditions of the surface before the simulation starts, affecting how the dunes will collapse onto one another after meeting its height threshold. Lastly, Ripple Amplitude adjusts the frequency of sand ripples.
Cellular Automata : Abelian Sand-Pile Model
The model of cellular automata is specified to the generate a computational algorithm that follows the behavioural outset of how particles move and form dunes, as well as how dunes collapse to create new dunes.. It’s formulation functions as follows: each site on a finite grid has an associated value that corresponds to the slope of the pile. This slope builds up as “grains of sand” are randomly placed onto the pile until the slope exceeds a specified threshold value at which time that site collapses, transferring sand into the adjacent.

The result of the simulation was fabricated with the CNC to physically examine the scale and different typologies dunes.
