Figure 7
The visual consists of two parts placed side by side. On the left side, a cube-like wireframe diagram is shown with solid and dashed edges. Black circular points are positioned at vertices and along edges, each labeled with numbers from 1 to 20. The front bottom edge shows points 1, 9, and 2. The bottom left edge includes 1, 12, and 4; the bottom right edge includes 2, 10, and 3; and the bottom back edge includes 4, 11, and 3. The mid-level includes labels such as 17, 18, 19, and 20. The upper front edge shows labels such as 5, 13, and 6, the top left edge shows 5, 16, and 8, and the top right edge shows 6, 14, and 7, and the top back edge shows 8, 15, and 7. Dashed lines show hidden edges inside the cube, forming an internal structure. On the right side, a three-dimensional corner view of a layered rectangular plate is shown resting above a circular base. The plate consists of multiple stacked layers. The top and bottom layers are labeled “Glass (2 elements slash layer)”. Between them, a central layered region is labeled “E V A plus solar cells plus PET (8 elements)”. The layers are shown as thin horizontal bands stacked together. A vertical dimension labeled “13.97 millimeters” is shown at the vertical edge, showing total thickness. Below the plate, a circular base is shown as a flat disk supporting the plate corner. A small coordinate indicator with axes labeled “X”, “Y”, and “Z” appears near the plate, with arrows pointing in three perpendicular directions. The X-axis extends towards the lower right, the Y-axis extends vertically upward, and the Z-axis extends towards the lower left side.Detail of a 20-node brick element and schematic model assembly for the examined glass-glass BIPV floor tile (ABAQUS).
