Control of element shape and alignment for 3D solution adaptive mesh generation

Abstract

A new 3D metric-aligned and metric-orthogonal method for anisotropic tetrahedral mesh generation is presented. The approach uses an advancing-point type point placement that aligns the elements with the underlying metric field and creates quasi-structured local topology. It is based on well-proven methodology and adds novel point-placement strategies that produce solution-adapted anisotropic meshes that are both sized and aligned with the solution gradients upon which the metric field is based. The overall methodology is extended to 3D from a previously developed 2D process. Results for analytical examples and a CFD simulation case are presented that demonstrate that aligned high-quality anisotropic tetrahedral meshes can be reliably generated.
