Hexahedral Sheet Extraction.
Michael J. Borden, Steven E. Benzley, Jason F. Shepherd · 2002
This work presents an algorithm for coarsening all-hexahedral meshes while maintaining all-hexahedral connectivity. The dual of a mesh is described and the constraints on hexahedral mesh modi cation are explained. This paper then describes how mesh coarsening can be performed by using the information contained in the dual.
