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.
