A) Influence of spatial discretization Δζ upon predicted conduction velocities for propagation along the axes f, s and n. B) Deviations in relative velocity, ${∊}_v={\stackrel{‒}{C}}_{\zeta }^v∕C_{\zeta }^v$ depend on the ratio Δζ to spatial extent of wave front, ΔX_ζ. Using APS, predicted C^v (black dotted trace) is independent of Δζ, at the cost of minor variations of the chosen conductivity value, σ_mf (pink trace)
