Qaudrilateral and Hexahedral Elements in Irregular Regions”, Proc. ASME Computers

True 3D mesh generation has often been limited to geometry that has been dissected into hexahedral volumes. N-faceted volume mapping and submapping are algorithms that automate this process when block-like elements are desired. N-faceted volume mapping is an application of the 3D mapping transformations derived by Cook[2], in which volumes are translated into a logical hexahedron. Volume submapping is the next step in the automation of the volume mapping of volumes that contain more than one logical hexahedral sub-volume. Volume submapping takes the pseudo decomposition method to a higher level by using mapped virtual surfaces to reduce decomposition of volumes. It uses “i-j-k ” traversals to locate the regions for cutting. Volume submapping is currentl
