Struct FluxGrid3D 

pub struct FluxGrid3D {
    pub nx: usize,
    pub ny: usize,
    pub nz: usize,
    pub dx: f64,
    pub values: Vec<f64>,
}

A 3-D scalar field stored in row-major order on a uniform Cartesian grid.

Index layout: values[i*(ny*nz) + j*nz + k] for cell (i, j, k).

Fields

nx: usize

Cells in the x-direction.

ny: usize

Cells in the y-direction.

nz: usize

Cells in the z-direction.

dx: f64

Uniform cell spacing.

values: Vec<f64>

Scalar field values.

Implementations

impl FluxGrid3D

pub fn new(nx: usize, ny: usize, nz: usize, dx: f64, fill: f64) -> Self

Create a grid filled with fill.

pub fn idx(&self, i: usize, j: usize, k: usize) -> usize

Flat index for cell (i, j, k).

pub fn get(&self, i: usize, j: usize, k: usize) -> f64

Read cell (i, j, k).

pub fn set(&mut self, i: usize, j: usize, k: usize, v: f64)

Write cell (i, j, k).

pub fn len(&self) -> usize

Total number of cells.

pub fn is_empty(&self) -> bool

True when the grid has no cells.

pub fn get_clamped(&self, i: isize, j: isize, k: isize) -> f64

Clamp-to-boundary accessor: returns the value at (i, j, k) with zero-gradient boundary conditions.

pub fn l2_norm(&self) -> f64

L2 norm of all values.

pub fn max_val(&self) -> f64

Element-wise maximum value.

pub fn min_val(&self) -> f64

Element-wise minimum value.
