A brief review of the Stefan problem of solidification from a mixture, andits main numerical solution methods is given. Simulation of this problem in 2Dor 3D is most practically done on a regular grid, where a sharp solid-liquidinterface moves relative to the grid. For this problem, a new simulation methodis developed that manifestly conserves mass, and that simulates the motion ofthe interface to second order in the grid size. When applied to an isothermalsimulation of solidification from solution in 1D at 50% supersaturation foronly 5 grid points, the motion of the interface is accurate to 5.5%; and for 10points the result is accurate to 1.5%. The method should be applicable to 2D or3D with relative ease. This opens the door to large scale simulations withmodest computer power.
