GGU-2D-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.

Before leaving the dialog box, you can use the "Normal", "Coloured" and "3D" option buttons to specify the type of contour diagram. Once the program has finished the difference calculation you will see dialog boxes for specifying contour line preferences in accordance with your selection.
