Title: 3D Boundary Conforming Delaunay Mesh Generation

Abstract: This work is motivated by the aim to support numerical methods to solve partial differential equations. Among them are finite element and finite volume methods. For these, a given domain must first be subdivided into many simple cells. The quality of the subdivision will tremendously affect the accuracy and convergence of the method. A boundary conforming Delaunay mesh is a partition of a polyhedral domain into Delaunay simplices. It is important in Voronoi-box based finite volume schemes. It allows to carry important qualitative properties from the continuous to the discrete level.

In this talk, we will study the meshing problems and algorithms related to the generation of three-dimensional good quality boundary conforming Delaunay meshes. Software implementation issues are discussed.
