Dai, Weizhong; Nassar, Raja An unconditionally stable finite difference scheme for solving a 3D heat transport equation in a sub-microscale thin film. (English) Zbl 1005.65084 J. Comput. Appl. Math. 145, No. 1, 247-260 (2002). The authors develop a finite difference scheme of the Crank-Nicolson type by introducing an intermediate function to the heat transport equation. The scheme contains two levels in time. It is shown by the discrete energy method that this scheme is unconditionally stable with respect to the initial values. The numerical procedure is employed to obtain the temperature rise in a gold sub-microscale thin film.
