Figure 4: Lattice2d element. Node numbering, DOF numbering and definition of integration point C.
Represents two-node lattice element. Each node has 3 degrees of freedom. The element is defined in x,y plane. The element features are summarized in Table 6.

| Description | Lattice element |
| Specific parameters | thick #(rn) width #(rn) gpCoords #(ra) |
| Parameters | thick: defines the out of plane (z-direction) thickness |
width: defines the width of the midpoint cross-section in the x-y plane with the point C at its centre |
|
gpCooords: array of the coordinates of the integration point C in the global coordinate system |
|
| Unknowns | Three dofs (u-displacement, v-displacement, w-rotation) are required in each node. |
