GGU-3D-SSFLOW: Step 9: Refine mesh in z-direction

First go to "z/Define section" to define a section through the system. The section is represented by pressing [Return]. It is apparent that the embankment subsurface is very coarsely modelled in z direction. Select the "z/Refine" menu item.

Click a total of three times in the embankment subsurface, so that the original layer now consists of four layers, as shown in the figure below. If you execute a wrong click, press [Backspace].
