Advancing Layer Surface Mesh Generation
Jasmeet Singh, Carl F. Ollivier Gooch · AIAA Scitech 2020 Forum · 2020
A new method of generating advancing layer surface meshes is demonstrated. We generate semi-structured quad-dominant meshes with the ability to have local control over the aspect ratio. Semi-structured two-dimensional anisotropic meshes in the boundary layer regions have been shown to have superior fluid flow simulation results. However, the discretization of the surfaces poses challenges in replicating the same for volume meshes. Beginning from an isotropic surface triangulation, we incrementally replace that mesh with an anisotropic mesh. Point placement in layers and local reconnection helps produce a valid surface mesh at each step of mesh generation. We demonstrate the ability of the meshing algorithm to tackle fairly complex geometries and coarse initial surface discretization.
