WebbA hexahedron is topologically equivalent to a cube. It has eight corners, twelve edges or sides, and six faces. Finite elements with this geometry are extensively used in modeling three-dimensional solids. Hexahedra also have been the motivating factor for the development of “Ahmad-Pawsey” shell Webbshape functions. Section 5 discusses the Piola transformation, which determines standard shape functions with linear ﬂux for irregular cells. Velocity interpolation functions, a precursor of the shape functions, are presented in section 6, followed by the shape functions themselves in section 7. Sections 8 and 9 present
