Abstract: Mesh is indispensable for many numerical simulations. Nowadays, geometries processed in high-performance numerical simulations become more and more complicated. Meanwhile, an increasingly higher requirement of fine-grained local features makes a one-billion mesh, which was unimaginable before, quite common. Consequently, mesh generation methods are supposed to be able to handle complicated geometries efficiently and capture fine local features adaptively at the same time. In addition, the transmission bottleneck when passing large-scale meshes to the solver needs to be avoided. Therefore, the development of more efficient parallel mesh generation softwares is of great practical value for promoting high-performance numerical simulations. Firstly, the latest research progress at home and abroad are summarized in terms of algorithms and software products. Secondly, the architecture design and key technologies of the in-house designed software SuperMesh are introduced. Finally, the development trend of parallel mesh generation technology is discussed.
