Shape function hexahedron
http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node27.html WebbThe shape functions will be defined locally on the tetrahedron. It should be noted that the global shape function is assembled from the local shape functions of the elements which share the same node . If it is assumed that the discretization is carried out with linear shape functions, the four vertexes used are the four grid nodes on the element.

Meshes are commonly used to compute solutions of partial differential equations and render computer graphics, and to analyze geographical and cartographic data. A mesh partitions space into elements (or cells or zones) over which the equations can be solved ...
WebbOur 3-D formulation using hexahedron elements rigorously embraces a posteriori error estimation scheme, a structural coupling scale-meshes strategy and an enrichment technique. Remeshing is only performed where it is needed, e.g., a vicinity of crack, through an error estimator based on the recovery stress procedure. WebbWe introduce General Implicit Function for 3D Shape (GIFS), which models the relationships between every two points instead of the relationships between points and surfaces. Instead of dividing 3D space into predefined inside-outside regions, GIFS encodes whether two points are separated by any surface. Experiments on ShapeNet show that …
