Struct PyLbm3dSimulation 

pub struct PyLbm3dSimulation { /* private fields */ }

A 3-D D3Q19 Lattice-Boltzmann simulation.

Supports BGK collision, periodic streaming, and bounce-back walls.

Implementations

impl PyLbm3dSimulation

pub fn new(config: &PyLbm3dConfig) -> Self

Create a new 3-D LBM simulation.

pub fn dimensions(&self) -> (usize, usize, usize)

Grid dimensions (nx, ny, nz).

pub fn step_count(&self) -> u64

Step count.

pub fn set_boundary(&mut self, x: usize, y: usize, z: usize, btype: LbmBoundary)

Set boundary at cell (x, y, z).

pub fn get_boundary(&self, x: usize, y: usize, z: usize) -> Option<LbmBoundary>

Get boundary at cell (x, y, z).

pub fn density_at(&self, x: usize, y: usize, z: usize) -> f64

Macroscopic density at cell (x, y, z).

pub fn velocity_at(&self, x: usize, y: usize, z: usize) -> [f64; 3]

Macroscopic velocity [ux, uy, uz] at cell (x, y, z).

pub fn step(&mut self)

Advance the simulation by one D3Q19 step (BGK + streaming + bounce-back).

pub fn run(&mut self, steps: u64)

Run n steps.

pub fn density_field(&self) -> Vec<f64>

Flat density field (length = nx * ny * nz).
