GGU-2D-SSFLOW: "User-defined section" menu item

After selecting this menu item you will see the following dialog box for defining the section:

For this type of evaluation the section course is no longer bound to the FEM nodes, but consists of a start and an end point. Using the "By hand" button you can specify the start and end points using numerical values instead of the mouse. If you have previously saved a section it can be loaded again using "Load section". The "Prev. section" button is only visible if a section has already been defined and loads the section defined immediately prior.

Once the section definition is completed by pressing [Return] the number of subdivisions can be specified in a further dialog box and whether potential, velocity or gradient is to be visualised. The number of subdivisions defines the number of points required for calculation of the section values. After confirming with "OK" the following dialog box opens:

You can now specify whether the section should be displayed in colour. You can also define the intercept of the x-axis with the y-axis by entering a value for "y0". In this case the "Use" check box must be activated. If you do not use this option, the x axis will intercept the y axis at the smallest y value. The section can also be displayed as a fence diagram. You can save the section in order to load it again at a later date (see above).

If you have activated "Show section course" using the menu item "Graphics preferences/Section legend", a location sketch is automatically displayed on the screen showing the system outline and the defined section.
