Summary of results ====================== The results obtained are satisfactory. The maximum difference (0.43%) is located on the outer surface of the parallelepiped (Point :math:`C`) at the lowest time :math:`t`. After :math:`10s`, this difference decreases, the maximum is then 0.054% (point :math:`O`: center of the parallelepiped). This test made it possible to test 3D modeling in transient linear mode with HEXA8 and PENTA6 meshes.
