The eXtreme Mesh deformation approach (X-MESH) is a new paradigm to follow sharp interfaces without remeshing and without changing the mesh topology. Even though the mesh does not change its topology, it can follow interfaces that do change their topology (nucleation, coalescence, splitting). To make this possible, the key X-MESH idea is to allow elements to reach zero measure. This permits interface relaying between nodes as well as interface annihilation and seeding in a time continuous… 


A Moving-Mesh Finite Element Method and its Application to the Numerical Solution of Phase-Change Problems
A distributed Lagrangian moving-mesh finite element method is applied to problems involving changes of phase and for the first time, two-phase Stefan problems in one and two space dimensions, paying particular attention to the implementation of the interface boundary conditions.
A hybrid extended finite element/level set method for modeling phase transformations
A hybrid numerical method for modelling the evolution of sharp phase interfaces on fixed grids is presented. We focus attention on two‐dimensional solidification problems, where the temperature field
Finite element method with local damage of the mesh
This work considers the finite element method on locally damaged meshes allowing for some distorted cells which are isolated from one another, and proposes an alternative finite element scheme which is optimally convergent and well conditioned.
Solving thermal and phase change problems with the eXtended finite element method
The application of the eXtended finite element method (X-FEM) to thermal problems with moving heat sources and phase boundaries is presented and the ability of the method to capture the highly localized, transient solution in the vicinity of a heat source or material interface is presented.
An Accurate Approximation of the Two-Phase Stefan Problem with Coefficient Smoothing
This work considers the heat transfer problems with phase change through a two-phase Stefan problem and proposes the method using smooth coefficient approximation based on the analytical smoothing of discontinuous coefficients through an error function with a given smoothing interval.
Two-phase Stefan problem with smoothed enthalpy
The enthalpy regularization is a preliminary step in many numerical methods for the simulation of phase change problems. It consists in smoothing the discontinuity (on the enthalpy) caused by the
A Simple Level Set Method for Solving Stefan Problems
A simple level set method for solving Stefan problems is presented. This method can be applied to problems involving dendritic solidification. Our method consists of an implicit finite difference
