Abstract
The effective generation of high quality quadrilateral surface meshes is an area of important research and development for the finfite community. This paper presents a new and unique procedure named "Surface Splicing," that allows for the generation of all quadrilateral surface meshes as well as the ability to edit these meshes via the dual. The dual contains the same data as the mesh but, unlike the mesh, the dual directly allows a unique visualization of how surface and volume elements interrelate and connect with one another. The dual also provides mesh connectivity information that is crucial in forming an all-quadrilateral surface mesh that can form the basis of a valid all hexahedral volume mesh.
