Abstract

For the bottleneck of time and memory in serial large-scale mesh generation, this study presents a method for large-scale parallel unstructured mesh generation. Firstly, the initial mesh is generated on the geometry and the initial mesh amount is controlled by the relative volume ratio and the optimal decomposition. Then, the initial mesh is decomposed by the graph partition method of graph theory. At last the parallel mesh generation is processed by split method. The proposed boundary judgement method based on the shared element solved the matching problem of the partition boundary nodes. Examples which illustrate the efficiency and applicability of this framework are presented and the examples show that this parallel mesh generation method can get high parallel efficiency and high quality tetrahedral mesh.

Key words
