13th International Conference on Fracture June 16–21, 2013, Beijing, China After a cleaning operation (that delete the too bad quality simplex elements), the last adaptive remeshing operation is done using the Distene/Inria remeshing tools, another iterative algorithm is involved in order to converge to a suitable mesh for FE computation and stress intensity factor extraction. The size map will now be build using the distance from any point of the volumetric mesh to the crack front nodes (using the previously defined size function (1)). When convergence is achieved the last stage is related to the boundary regeneration in order to separate both sides of the crack surface. In this respect a global/local coloring algorithm is used. The fast global approach is used on continuous zone without branching nodes while the local approach is required to deal with branching nodes. -5-
