WebJul 1, 2024 · 24. Understanding lattice Boltzmann boundary conditions through moments. 25. A simple example Imagine we want to solve the 1D advection–diffusion equation ∂φ ∂t + u ∂φ ∂x = D ∂2φ ∂x2 which can be written ∂φ ∂t + ∂ψ ∂x = 0 where ψ = uφ − D ∂φ ∂x . The (macroscopic) quantities of interest are φ and ψ. WebThe pressure boundary condition is particularly confusing as pressure enters Lattice Boltzmann simulations in a subtle way. In our Lattice Boltzmann simulation, pressure is related to density by ΔP ∝ Δρc s 2; the constant in front of Δρ relates to how we scaled our simulation. To set f at each boundary, we follow a procedure similar to the "Boundary …
