GGU-3D-SSFLOW: "Difference" menu item

A contour diagram of equal water level differences can be generated using this menu item. To do this, append to the current data set an FEM data set previously computed and saved with the results. The program then adopts the potential differences between the two computations. More detailed descriptions (compatibility between data sets, positions of soils, boundary conditions) can be taken from the dialog box for this menu item.

The sign can be reversed for subsequent visualisation of the difference lines. You can also specify the type of contour line presentation by activating or deactivating the "Coloured" check box in the dialog box. If you exit the dialog box using "OK", you first import the second file for difference formation via a file selector. Once the program has completed the difference calculation, you will see dialog boxes for specifying contour line preferences in accordance with your selection.
