Summary
A boundary layer mesh is a mesh with dense element distribution in the normal direction along specific boundaries. PostBL is a utility to generate boundary layer elements on an existing mesh model. PostBL supports creation of hexahedral, prism, quad, and tri boundary layer elements. It is formulated as an algorithm in MeshKit, which is an open-source library for mesh generation functionalities. Typically, boundary layer mesh generation is a premeshing process; in this effort, however, we start from a model that has already been meshed. Boundary layer elements can be generated along the entire skin or on selected exterior or internal surface boundaries. PostBL mesh operation can be coupled with other MeshKit meshing operations such as Jaal, NetGen, TetGen, and CAMAL and custom meshing tools such as RGG. Simple examples demonstrating generation of boundary layers on different mesh types and the OECD Vattenfall T-Junction benchmark hexahedral mesh are presented.
