Struct PyLbmConfig 

pub struct PyLbmConfig {
    pub width: usize,
    pub height: usize,
    pub viscosity: f64,
    pub body_force: [f64; 2],
}

Configuration for a 2-D D2Q9 Lattice-Boltzmann simulation.

Fields

width: usize

Grid width (number of cells in X direction).

height: usize

Grid height (number of cells in Y direction).

viscosity: f64

Kinematic viscosity (nu). Controls the relaxation rate.

body_force: [f64; 2]

External body-force acceleration [fx, fy] applied to the fluid.

Implementations

impl PyLbmConfig

pub fn new(width: usize, height: usize, viscosity: f64) -> Self

Create a new LBM configuration.

pub fn lid_driven_cavity() -> Self

Create a default lid-driven cavity configuration (64×64).

pub fn omega(&self) -> f64

Compute the relaxation parameter omega from viscosity.

omega = 1 / (3 * nu + 0.5)
