Struct PyLbmBinding 

pub struct PyLbmBinding { /* private fields */ }

PyO3-style binding handle for a 2-D LBM simulation.

Uses the PyLbmGrid type (D2Q9 BGK) defined earlier in this file.

Implementations

impl PyLbmBinding

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

Create a new LBM binding with the given grid dimensions and viscosity.

pub fn from_config(config: PyLbmConfig) -> Self

Create from an explicit PyLbmConfig.

pub fn grid_width(&self) -> usize

Grid width (number of cells along X).

pub fn grid_height(&self) -> usize

Grid height (number of cells along Y).

pub fn cell_count(&self) -> usize

Total number of cells.

pub fn step(&mut self)

Advance the simulation by one LBM step.

pub fn run_steps(&mut self, n_steps: u32)

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

Return velocity field as interleaved [ux0,uy0, ux1,uy1, …].

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

Return velocity magnitude (speed) for each cell as a flat array.

pub fn mean_density(&self) -> f64

Mean density across all cells.
