GGU-3D-SSFLOW: "New" menu item
After going to the "New" menu item, define the number of element layers for your system in the dialog box.

Element layer numbering begins at the bottom with 1, the planes that bound on an element layer are also continuously numbered from top to bottom. Because the system ends at the bottom, the number of element layers is one less than the number of planes. To aid orientation, the active layer and plane are labelled and coloured in the Layer/plane legend (see Figure 6).
