Cover Story: Simulating the melting of ice layers is a complex problem, as the computational domains—represented by the red region for water and the blue region for ice—evolve step by step. Rather than employing the conventional finite element method, this work proposes an optimization-based finite difference discretization. The key advantage of this approach lies in its ability to vectorize the assembly procedure for the discretization matrix, significantly reducing computational time at each simulation step. The finite difference scheme extends the standard nine-point Laplacian approximation for rectangular meshes. Using an optimization process based on the least-squares solution of overdetermined systems, the method calculates finite difference weights for general quadrilateral meshes. View this paper
