Problem statement

Geometry
Semi-infinite solid (half-space), x ≥ 0, uniform initial temperature.
Material
Isotropic conductivity k and thermal diffusivity α = k/(ρc).
Boundary conditions
Surface temperature suddenly stepped to T_s at t = 0.
Measured quantity
Transient profile (T−T_s)/(T_i−T_s) = erf(x/2√(αt)) at chosen depths/times.

Script

Lands with the scripting engine (see Documentation) — this setup will be runnable from commands, no manual rebuild needed.

Results comparison

The solver core is still in development — there's no result yet. It'll appear here right after the first run, no retouching.
