The purpose of this research is to generate high-aspect-ratio cells for structured grids in the vicinity of boundaries for wall dominated phenomena such as viscous layers in aerodynamic applications. When such domains are discretized for complex geometries, it is important that the grid fits the boundaries well, and this becomes even more difficult to achieve with strongly curved boundaries. Domain decomposition simplifies this problem by subdividing the domain into multiple blocks and makes the task of meshing complex geometries more manageable.
