    pub nx: usize,
    pub ny: usize,

}

Heat-diffusion grid and time-step description.

Fields

nx: usize

Number of grid points along x.

ny: usize

Number of grid points along y.

dx: f64

Cell spacing along x (m).

dy: f64

Cell spacing along y (m).

dt: f64

Time-step (s).

alpha: f64

Thermal diffusivity α (m²/s).

temperature: Vec<f64>

Current temperature field, row-major (j * nx + i) (K).

Implementations

impl HeatGrid

pub fn len(&self) -> usize

Total number of grid points.

pub fn is_empty(&self) -> bool

Returns true when the grid has zero extent.

pub fn cfl(&self) -> f64

Compute the von-Neumann CFL coefficient α dt (1/dx² + 1/dy²).

pub fn is_stable(&self) -> bool

Returns true when the explicit forward-Euler scheme is stable (CFL ≤ 1/2 in 2D).

Trait Implementations

impl Clone for HeatGrid

fn clone(&self) -> HeatGrid

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HeatGrid

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

Formats the value using the given formatter.

impl PartialEq for HeatGrid

fn eq(&self, other: &HeatGrid) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
