Three-dimensional anisotropic mesh adaptation for phase change problems
A three-dimensional adaptive strategy for the finite element simulation of phase change problems is presented, discussed and validated. A semi-phase-field formulation is used for the solution of the Stefan problem. The adaptive method is based on the definition of edge length using a solution dependent metric and produces strongly anisotropic meshes. Numerical results illustrating the performance and accuracy of the proposed method are presented.
