Скачать или смотреть Diffusion-Limited Aggregation (DLA) – Stop When Centre Filled | 101×101 Grid Simulation in Python

This video shows a simulation of diffusion-limited aggregation (DLA) on a 101×101 grid, with a stopping condition: the simulation terminates once a particle becomes anchored at the central point.

💻 Programming Language: Python 3
📦 Libraries Used: NumPy, Matplotlib
🧮 Grid Size: 101×101 (ensures a unique central lattice point)
🔢 Stopping Condition: Simulation halts when centre is occupied
⚙️ Boundary: Outer edge pre-filled with anchored particles
🎥 Visualisation: Only anchored particles are shown, updated per attachment

Each particle starts at the grid centre and performs a two-dimensional random walk. If it reaches a location adjacent to an anchored site or the boundary, it sticks and becomes part of the aggregate. The simulation ends once a particle sticks at the centre, where subsequent particles would immediately anchor.

This simulation is part of the Computational Physics (PH413) course at KAIST, Spring 2025.
