VCL Lunch Talk: TetGen, a Delaunay Tetrahedral Mesh Generator: Hang Si of the Weierstrass Institute

Seminar: Departmental | October 12 | 12-1 p.m. | Soda Hall, VCL - 510 Soda

Hang Si, Weierstrass Institute

Electrical Engineering and Computer Sciences (EECS)


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.
