As the first step in the mathematical modelling of two-dimensional heat flow and stress generation in a solidifying steel ingot with corrugations, this investigation was conducted to assess the accuracy, stability and cost of different numerical methods for solving complex, transient, heat-conduction problems involving non-linear boundary conditions, phase change, variable properties and irregular geometry. Several different formulations for the standard finite-element method, the matrix method of Ohnaka and the alternating-direction implicit finite-difference method have been examined; and predictions using these techniques have been compared to analytical solutions for two relevant problems.
