The finite element method is used to model the solidification process in a sand casting. With a relatively coarse mesh, there is good agreement between numerical and experimental results. An implicit-explicit time- stepping algorithm demonstrated significant computer time savings when the appropriate solver was implemented. Consideration is also given to the problem of capacitance matrix lumping when quadratic elements are employed.
