GGU-CANTILEVER: "Groundwater potentials" menu item
You can define additional potentials anywhere along the wall (see “Theoretical principles: Water pressure approch using flow conduits”).

In the above example a potential of 4.0 m below the top of wall at the left and right of the cantilever wall has been entered at a depth of 2.0 m below the top of wall. Additional potentials will only be considered if the water pressure approach using flow conduits has been selected (see menu item “Editor 1/Groundwater”).
Instead of the potential values in [m], you can enter the values as water pressures in [kN/m²] to the left and right of the cantilever wall. To do this, click on the "Switch to: Enter water pressure" button.
