A new node-based parallel mesh generation technique based on the free mesh method (FMM) is presented. The technique is featured by a node-by-node algorithm and it is quite suitable for massively parallel computing. The mesh is generated in a local area around each node by searching neighboring nodes using the multi-level buckets. Local elements generated by the present method are founded on constrained Delaunay triangulation, so that even complex boundary shapes such as cracks can be treated in a local manner. For a numerical example, a crack model is divided into finite element mesh by a local approach, and it is shown that the present method can achieve both of robustness in mesh generation for complex shapes and high efficiency in massively parallel environments.
