Parallel anisotropic mesh adaptation with boundary layers for automated CFD simulations

This paper presents a set of parallel procedures for anisotropic mesh adaptation accounting for mixed element types used in boundary layer meshes, i.e., the presented procedures operate in parallel on distributed boundary layer meshes. The procedures accept anisotropic mesh metric field as an input for the desired mesh size field and apply local mesh modifications to adapt the mesh in order to match the specified mesh size field. The procedures fully account for the parametric geometry of curved domains and maintain the semistructured nature of the boundary layer elements. The effectiveness of the procedures are demonstrated based on three viscous flow examples that include the ONERA M6 wing, a heat transfer manifold, and a scramjet engine.
