Automatic Tetrahedral Mesh Generation using Advancing Front Technique with Delaunay Node Searching

전진경계법에서 Delaunay 탐색조건을 이용한 사면체 요소망의 자동 생성

A unstructured tetrahedral mesh generation algorithm has been presented. To make better meshes in interior region using an advancing front technique, a connecting operator has been developed in addition to the existing operators. Before applying digging operators that generate new nodes inside of a meshing region, a connecting operator is employed that uses existing nodes which satisfy certain conditions for producing well-conditioned elements if possible. By introducing this new operator, tetrahedral meshing process becomes more robust and produces better quality of meshes.
