Trilinear hexahedron
WebA 658-element, three-dimensional finite-element model of the thorax and neck using eight-node trilinear hexahedron elements was constructed for investigating the current distribution in the thorax. A three-dimensional finite-element code was developed to solve the generalized Laplace equation with Dirichlet and homogeneous Neumann boundary … WebThe hexahedron elements with six and eight integration points converge fastest, and show little influence of the resolution. The serendipity element and the incompatible-modes element follow closely. Both the Rannacher–Turek element and the hexahedron element with six sub-tetrahedra require both more iterations, and are trailed by the staggered grid …

To develop the stiffness matrix for a 3D linear brick, it is not sufficient to only keep the first-order Taylor expansion terms. Second-order Taylor expansion terms are also added, however, only the ξ η ζ cross-derivative terms are nonzero in the expansion.
