#### 4.2.2.3 Shell on top of solid element

When a shell is coincident with the face of a solid element, we assume that the face of the solid element coincides with the back face () of the shell element. This means that the solid element nodal displacements on that face coincide with the shell nodal displacements . Therefore, when we use UnpackLM for those solid elements, we should reassign the DOF ID's of the displacements to those of the displacements stored in that same node.
