The main idea of the cellular automata technique is to divide a specific part of the material into one-, two-, or three-dimensional lattices of finite cells, where cells have clearly defined interaction rules between each other. Each cell in this space is called a cellular automaton, while the lattice of the cells is known as cellular automata space.
N(i) – neighbours of the ith cell, i – state of the ith cell
Simple Grain Growth CA algorithm
Von Neumann neighborhood
•absorbing boundary conditions – the state of cells located on the edges of the CA space are properly fixed with a specific state to absorb moving quantities.
•periodic boundary conditions – the CA neighborhood is properly defined and take into account cells located on subsequent edges of the CA space.
1. At the beginning of simulation (square diagonal d and circle with radius r).
2. After simulation (square with diagonal d and circle with radius r).
