All hexahedral boundary layers generation

Abstract : Boundary layers generation has recently become one of the most sought-after features in mesh generation. But behind this single feature hides a lot of different capacities that range from the most basic, like extruding a layer from a surface, to imprinting, cross- imprinting and multi-normals capabilities that are much more challenging to develop. This paper aims at implementing all those features using hexahedral elements only and is based on a previously developed automated hexahedral mesh generator based on the octree method. Both points, octree and hexahedra, implying some constraints that this paper will address in a very pragmatic way. Indeed, we view automatic meshing from the industrial user’s point of view: no mesh, no run, consequently this work’s philosophy has been always to favor automaticity and genericity over element’s quality and geometric approximation.
