Discussion The Eulerian method of studying fluid motion is not as “natural” as the Lagrangian method since the fundamental conservation laws apply to moving particles, not to fields. 4-8C

A Practical Introduction to the Lattice Boltzmann Method
www.ndsu.eduand method that locally conserves mass and momentum will obey some kind of continuity and Navier Stokes equations and it was shown that the lattice gas methods could be used to simulate (rather noisy) hydrodynamics. However, the lattice gas methods had several drawbacks consisting ... Lagrangian multipliers to minimize this functional. With ...
