Abstract
A self-adaptive moving mesh for enthalpy formulations of diffusion driven phase change problems is described. The PDE is approximated by a finite element method on a moving, irregular mesh. The mesh is determined by a novel equidistribution principle and is concentrated in the phase transition regions and uniform in regions of pure phase.Keywords
