Why use lattice Boltzmann method?
In comparison with the conventional CFD methods, the advantages of LBM include simple calculation procedure, simple and efficient implementation for parallel computation, easy and robust handling of complex geometries, and others.
What is the lattice in physics?
In physics, a lattice model is a physical model that is defined on a lattice, as opposed to the continuum of space or spacetime. Lattice models originally occurred in the context of condensed matter physics, where the atoms of a crystal automatically form a lattice.
What is called space lattice?
The three-dimensional network of imaginary lines connecting atoms is called the space lattice. A crystal is an arrangement in three dimensions of atoms or molecules in repetitive patterns.
Is the lattice Boltzmann method based on particle models?
Lattice Boltzmann method (LBM) is a methodology based on the microscopic particle models and mesoscopic kinetic equations.
How is the lattice Boltzmann method used for UID?
In the last two decades, the Lattice Boltzmann method (LBM) has emerged as a promising tool for modelling the Navier-Stokes equations and simulating complex uid ows. LBM is based on microscopic models and mesoscopic kinetic equations.
What are the general principles of the Boltzmann method?

How is the Boltzmann distribution related to continuum kinetic theory?
This distribution relates to the standard one-body Boltzmann distribution function of continuum kinetic theory. The system evolves toward equilibrium through the relaxation of the distribution function to its equilibrium form.
