TetGen is a software tool, written in C++, for the generation of high-quality tetrahedral meshes. It uses efficient algorithms that lead to boundary constrained and conforming Delaunay tetrahedralizations. It uses advanced techniques in computational geometry to achieve a robust implementation. To fit special requirements arising in numerical simulations, many features are available for adaptively improving the mesh qualities. This talk presents an overview of the problems and the current algorithms used in TetGen. Some recent and new development of TetGen will be discussed.
Hang Si is empolyed by Weierstrass Institute (WIAS) in Berlin. His main research interest is tetrahedral mesh generation and the discrete and computational geometry problems behind it. The goal is to develop efficient algorithms for automatically generating tetrahedral meshes suitable for numerical methods such as finite element and finite volume methods. He developed the software, TetGen, a Delaunay tetrahedral mesh generator. It is freely available for academic use.
Hang Si got his B.S. in Electrical Engineering in Hangzhou University in 1994, and got his M.S. in Computer Science in Zhejiang University in 2002. He joined the research group “Numerical Mathematics and Scientific Computing” of WIAS in 2002. He received his Ph.D from the Institute of Mathematics of Technische Universitaet Berlin in 2008.
