摘要:

This short course focuses on the fundamental problems in finite element mesh generation, which automatically generate boundary-preserving and good quality triangular and tetrahedral meshes.  Begin with the Delaunay triangulations theory; we will describe optimal algorithms to generate good quality triangular meshes for arbitrary polygonal domains. We then move on to tetrahedral mesh generation in 3d, which has many theoretical and practical challenges. We will first review the main difficulties and their related theories in discrete and combinatorial geometry and then describe good heuristic algorithms to overcome them. Practical techniques to achieve a robust and efficient implementation will also be discussed.
