“CleanUp”, written to improve an all quad mesh, looks at improving node connectivity, boundary and flange patterns, quad shape, and to some extent, quad size. Unless an all quadrilateral (quad) finite element mesher is of a high quality, the mesh it produces can contain misshapen quads. This paper will describe “CleanUp”, written to improve an all quad mesh. CleanUp looks at improving node connectivity, boundary and flange patterns, quad shape, and to some extent, quad size. CleanUp is currently used in conjunction with the Paver algorithm developed by Sandia National Laboratories and is a part of their CUBIT software.
