Generation of unstructured tetrahedral meshes by advancing front technique

TLDR

The study presents an algorithm for generating unstructured tetrahedral meshes using the advancing front technique. The algorithm constructs tetrahedral elements, employs measures to avoid difficult situations, and uses a control line/surface scheme to specify element size. Numerical examples demonstrate the algorithm’s performance.

Abstract

Abstract An algorithm for generating unstructured tetrahedral meshes by the advancing front technique is presented. Emphasis is placed on the construction of tetrahedral elements. Several measures are employed to prevent difficult situations. A control line/surface scheme is used to specify element size. Numerical examples are provided to show the performance of the algorithm.
