AB - <p style="text-align: justify;">A novel method for boundary constrained tetrahedral mesh generation is
proposed based on Advancing Front Technique (AFT) and conforming Delaunay triangulation. Given a triangulated surface mesh, AFT is firstly applied to mesh several
layers of elements adjacent to the boundary. The rest of the domain is then meshed
by the conforming Delaunay triangulation. The non-conformal interface between two
parts of meshes is adjusted. Mesh refinement and mesh optimization are then preformed to obtain a more reasonable-sized mesh with better quality. Robustness and
quality of the proposed method is shown. Convergence proof of each stage as well as
the whole algorithm is provided. Various numerical examples are included as well as
the quality of the meshes.</p>
