Struct NavierStokesKernelDispatcher 

pub struct NavierStokesKernelDispatcher { /* private fields */ }

GPU-accelerated Navier-Stokes pressure-Poisson dispatcher.

Implementations

impl NavierStokesKernelDispatcher

pub fn new() -> Self

Create a new dispatcher.

pub fn is_available(&self) -> bool

Returns true when a usable GPU backend is available.

pub fn dispatch_pressure_jacobi( &self, grid: &PressureGrid, ) -> GpuResult<Vec<f64>>

Run a single Jacobi sweep of the pressure-Poisson equation.

Returns the updated pressure field. Boundary cells are held fixed (Dirichlet). The CPU reference path can be re-used for validation by calling Self::cpu_reference_jacobi.

Errors

Returns GpuError::BackendUnavailable when compiled without the gpu feature, or GpuError::InvalidInput when the grid is degenerate.

pub fn dispatch_pressure_solve( &self, grid: &PressureGrid, n_sweeps: usize, ) -> GpuResult<PressureSolveOutput>

Run n_sweeps Jacobi sweeps and return the final pressure field alongside the L2 residual after the last sweep.

Errors

Returns GpuError::BackendUnavailable when the backend is not ready.

pub fn cpu_reference_jacobi(grid: &PressureGrid) -> Vec<f64>

CPU reference implementation of one Jacobi pressure sweep — public for fallback and validation. Boundary cells are held fixed.

pub fn residual_l2(grid: &PressureGrid) -> f64

L2 residual of the Poisson operator on the interior of grid.

Trait Implementations

impl Debug for NavierStokesKernelDispatcher

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for NavierStokesKernelDispatcher

fn default() -> NavierStokesKernelDispatcher

Returns the “default value” for a type.
