"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. " - Shape function hexahedron
