“…An equivalent 'metric-based' advancing front surface mesh generation algorithms is presented by Cuilliere in [44]. A more exotic metric-based approach based on packing ellipses has been devised by Yamada and coworkers [45] and has been used more recently by Lo and Wang in [46].…”

“…The second stage involves optimizing boundary mesh by remeshing the surface mesh partly. The ball-packing method (Lo and Wang, 2005b, Yamakawa and Shimada, 2003; Liu et al , 2008) and the node insertion/deletion method (Greg, 2001) are combined in this stage, and the results show that this approach is efficient and can generate high-quality meshes. The third stage involves remeshing some portions of the volume mesh by combining the ball-packing method and the Delaunay mesh generation method.…”

Purpose During the industrial design process, a product is usually modified and analyzed repeatedly until reaching the final design. Modifying the model and regenerating a mesh for every update during this process is very time consuming. To improve efficiency, it is necessary to circumvent the computer-aided design modeling stage when possible and directly modify the meshes to save valuable time. The purpose of this paper is to develop a method for mesh modifications. Design/methodology/approach In contrast to existing studies, which focus on one or a class of modifications, this paper comprehensively studies mesh union, mesh gluing, mesh cutting and mesh partitioning. To improve the efficiency of the method, the paper presents a fast and effective surface mesh remeshing algorithm based on a ball-packing method and controls the remeshing regions with a size field. Findings Examples and results show that the proposed mesh modification method is efficient and effective. The proposed method can be also applied to meshes with different material properties, which is very different with previous work that is only suitable for the meshes with same material property. Originality/value This paper proposes an efficient and comprehensive tetrahedral mesh modification method, through which engineers can directly modify meshes instead of models and save time.
