An algorithmnext term for previous termtetrahedral mesh generation based on conforming constrained Delaunay tetrahedralizationnext term

摘要

An unstructured previous termtetrahedral mesh generation algorithmnext term for 3D model with constraints is presented. To automatically generate a previous termtetrahedral meshnext term for model with constraints, an advancing front previous termalgorithmnext term is presented previous termbased on conforming constrained Delaunay tetrahedralizationnext term (CCDT). To reduce the number of visibility tests between vertices with respect to model faces as well as the computation of previous termconstrained Delaunaynext term tetrahedra, a sufficient condition for DT (previous termconstrained Delaunay tetrahedralizationnext term whose simplexes are all previous termDelaunay)next term existence is presented and utilized coupled to uniform grid and advancing front techniques in our previous termalgorithm. The meshnext term generator is robust and exhibits a linear time complexity for mechanical models with uniform density distribution.
