Parallel Delaunay Refinement and Space -Time Meshing
A tetrahedron is acute if all its dihedral angles are less than 90°. Triangulations of three-dimensional domains with acute tetrahedra are useful in mesh generation. We give several constructions for tiling space with acute tetrahedra.

Three Novel Algorithms for Triangle Mesh Processing: Progressive Delaunay Refinement Mesh Generation, Mls-Based Scattered Data Interpolation and Constrained Centroid Voronoi-Based Quadrangulation
The last problem I address in the thesis is the conversion of triangle meshes to quadrilateral meshes. Although triangle meshes are preferred in most of applications, quadrilateral meshes show more stability in scientific computation. Because most of acquisition and mesh generation methods result …

Parallel Two-Dimensional Unstructured Anisotropic Delaunay Mesh Generation for Aerospace Applications
… of point-insertion, triangulation, and Delaunay refinement. Applications focusing on high-lift design or dynamic stall, or numerical methods and modeling test cases focus on two-dimensional domains. This push-button parallel mesh generation approach can generate high-fidelity …

Tetrahedral Mesh Improvement, Algorithms and Experiments
… appearance of slivers in large three-dimensional Delaunay meshes has been reported as early as 1985. They persist even after treatment with the Delaunay refinement algorithm. Cheng et al. proposed to remove slivers by assigning real weights to the points and change the Delaunay to the weighted …
