• There is a typographical error in Equation 13, which
should instead read:
⎧ = −∇(k(T)∇𝜆), ∀ 𝐱 ∈ Ω ⎪ ⎨ 𝜆(𝐱, t) = 0, ∀ 𝐱 ∈ Ω, t = tf ⎪ k(T) 𝜕𝜆 = 2(T − Y), ∀ 𝐱 ∈ S, 0 < t < t f ⎩ 𝜕n 1 𝜕𝜆 𝜌cp (T) 𝜕t
• The values in Table 4 should be updated to contain the
values in the table below. The values in the published version of the table are incorrect, caused by a bug in the averaging procedure in the error processing software. This bug does not affect the results presented in Figure 6 nor does it affect the global error of 12% presented in the text of the document.
