The considered soil type has the input dialog box as shown in the following figure.
Soil volume/Soil volume sets
In area (1), you can assign the massif to the soil solids or, alternatively, soil volume sets of the "Continuous Solids" type that it should consist of. This can be done directly by entering the corresponding number or by using the graphical selection.
Geometrie des Bodenmassivs
For the existing soil type, the geometry is defined by the geometry of the applied soil solids or sets. Thus, no entry is required in area (2).
Options
If you want to consider the ground water level in the further analysis of the soil massif, select the corresponding check box in the Options section. For the surface, it is necessary to enter the surface number of a previously modeled ground water level surface.
