Abstract
Meshes are commonly generated as a successor to geometric models in computational design and analysis. Computational analyses are performed in industry and academia for use in research, development, and manufacturing. The accuracy of these analyses depends on the fidelity of the geometric models and meshes. Element quality also plays an important role. Whereas most mesh generation strategies focus on element quality, this should be secondary to accurate representation of the real-world object. In McLaurin and Shontz (Automated edge grid generation based on arc-length optimization. In: Proceedings of the 22nd International Meshing Roundtable, pp. 385–403, Springer, Berlin, 2014), we recently proposed an automated method for generation of optimal edge grids via minimization of the arc-length deficit via a local optimization technique. In this paper, we explore the use of several different global optimization and adaptivity strategies for generation of optimal edge grids. Our results demonstrate the robustness and accuracy of our global optimization and adaptivity method for edge grid generation. We also discuss potential extensions of our method which incorporate a computational budget, achieve greater efficiency through development of a hybrid method based on local and global optimization and adaptivity, and incorporate symmetries.
