Module gpu_thermal 

GPU-accelerated thermal computation (CPU mock backend via Rayon).

Implements a parallel finite-difference heat equation solver that mirrors the structure of a GPU compute dispatch. The “GPU” here is simulated via Rayon parallel iterators, making it easy to swap in a real GPU backend later.

Structs

GpuThermalSolver

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

HeatSource

Volumetric heat source specification.

Enums

ThermalBc

Boundary condition type for thermal simulations.

Functions

gpu_heat_diffusion

Perform one parallel heat-equation update step (mock GPU dispatch).

gpu_heat_source

Apply volumetric heat sources to the temperature field (mock GPU kernel).

temperature_gradient

Compute the temperature gradient at every interior cell using central differences.

thermal_boundary_apply

Apply boundary conditions to the temperature field.

thermal_equilibration

Check whether the temperature field has reached thermal equilibrium.
