Application of smooth mixed meshes based on metric identity in aerospace analysis and design

Abstract

An applicable method for generating mixed meshes around simple and medium complex configurations is presented. Core part of the mesh generation strategy is a smooth meshing of the boundary layer region by structured hexahedrons and prisms applying smoothing based on solving face-weighted Laplacian equations. A preconditioning of the point set for triangulation by shear and edge-weighted average affine invariant transformation is proposed to stabilize end accelerate constrained Delaunay volume triangulation. An examples of the mesh generation strategy is shown for a generic transport aircraft in high-lift configuration.
