Struct GpuThermalSolver 

pub struct GpuThermalSolver {
    pub nx: usize,
    pub ny: usize,
    pub nz: usize,
    pub diffusivity: f64,
    pub dx: f64,
    pub dy: f64,
    pub dz: f64,
    pub temperature: Vec<f64>,
}

GPU-accelerated (CPU mock) thermal solver for 3-D structured grids.

Solves the heat equation:

  ∂T/∂t = α ∇²T + Q

where α is the thermal diffusivity and Q is a volumetric heat source.

Grid layout: row-major, index [iz * ny * nx + iy * nx + ix].

Fields

nx: usize

Number of cells in the x-direction.

ny: usize

Number of cells in the y-direction.

nz: usize

Number of cells in the z-direction.

diffusivity: f64

Thermal diffusivity (m²/s or simulation units).

dx: f64

Grid spacing in x (m).

dy: f64

Grid spacing in y (m).

dz: f64

Grid spacing in z (m).

temperature: Vec<f64>

Current temperature field, length nx * ny * nz.
