TetGen, Version 1.5, User’s Manual

Abstract: TetGen is a software for tetrahedral mesh generation. Its goal is to generate good quality tetrahedral meshes suitable for numerical methods and scientific computing. It can be used as either a standalone program or a library component integrated in other software.

The purpose of this document is to give a brief explanation of the kind of tetrahedralizations and meshing problems handled by TetGen and to give a fairly detailed documentation about the usage of the program. Readers will learn how to create tetrahedral meshes using input files from the command line. Furthermore, the programming interface for calling TetGen from other programs is explained.

keywords: tetrahedral mesh generation, Delaunay tetrahedralization, weighted Delaunay triangulation, constrained Delaunay tetrahedralization, mesh quality, mesh refinement, mesh adaption, mesh coarsening
