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 Laplace equations. A preconditioning of the point set for triangulation by shear and edge-weighted average affine invariant transformation is proposed to stabilize and accelerate volume triangulation. In order to generate a smooth transition from the highly stretched structured boundary layer cells to the volume triangulation an anisotropic volume triangulation is used, where the derivation of the correct metrics is a key component. Benefits of the mesh generation strategy are outlined comparing calculations on different meshes to experimental data for the ONERA M6 wing.
