WebbTypically, the 3D solid finite element shapes can be tetrahedron or hexahedron with either flat or curved surfaces. Even that the number of nodes in each solid finite element is different, each node of the finite element will have three translational degrees of freedom. WebbThe shape function (5.29) transforms a hexahedron in the xyz-coordinate system into a cube in the ξηζ-coordinate system. As a result, the volume integral over a hexahedron …
