Sweeping algorithms provide the ability to generate all hexahedral meshes on a wide variety of three-dimensional bodies. The work presented here provides a method to refine these meshes by first defining a path through either the source or the target mesh and next by locating the sweeping layer to initiate the refinement. A major contribution of this work is the ability to automatically find a minimal distance path through the target or source mesh. The refinement is accomplished by using the pillowing procedure as proposed by Mitchell.
