GGU-STABILITY: Step 8: Define reinforced soil wall preferences (Ex. 1)
Select the "Nail wall/Preferences" menu item and activate the "Calculate wall" check box. In the "Wall consists of:" group box select "Geosynthetics" as the nailing element.

The faces are sections of the defined terrain polygon course. They are continuously numbered from left to right. By assigning the (face) number you define which section of the terrain polygon course is the reinforced slope face (also see Figure 33 in Section “"Preferences" menu item“). Assign the number 2 for "Face 1" because this is the reinforced slope face in the worked example. Confirm the remaining defaults with "OK".
