UNSTRUCTURED TETRAHEDRAL MESH GENERATIONTECHNOLOGY

摘要

We present a robust unstructured tethahedra mesh generation technology. This technology is a com-bination of boundary discretization methods, an advancing front technique and a Delaunay-basedmesh generation technique. For boundary mesh generation we propose four different approaches us-ing analytical boundary parameterization, interface with CAD systems, surface mesh refinement, andconstructive solid geometry. These methods allow us to build a flexible grid generation technology witha user friendly interface.
