LBM simulates fluid flow using a grid of nodes, each representing a small volume of the fluid. At each time step, particles distribute themselves across these nodes according to specific rules that conserve mass and momentum. The key components are:
1. Collision Step: Particles at each node collide and redistribute their velocities. 2. Streaming Step: Particles move to adjacent nodes based on their velocities.
These steps are repeated iteratively to simulate the evolution of the fluid over time.
