Aligned metric-based anisotropic solution adaptive mesh generation

Abstract

A new aligned metric-based anisotropic mesh generation procedure is presented. The approach uses an advancing-point type point placement that aligns the elements with the underlying metric field. It is based on well-proven methodology combined with new novel point-placement strategies that are aligned with an underlying metric field. This simple strategy produces solution-adapted anisotropic meshes that are optimal in size and alignment with the solution gradients upon which the metric field is based. The overall methodology is implemented in a 2D process that is fully extendable to 3D. Results for several analytical and actual CFD simulation examples are presented that demonstrate that aligned high-quality anisotropic meshes that are optimal for the solution process can be reliably generated.
