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

The coordinates of existing nodes can be edited. Three options are available for this:

• "Via a table"
  You can edit the coordinates of existing nodes or, alternatively, enter the coordinates of new nodes.

If you need to edit the current number of nodes click the "x FEM nodes to edit" button and enter the new number of nodes. You can navigate through the table using "Forw." and "Back". The new nodes will be assigned the default depths as z values (see "z/Default depths" menu item). If you set the number of nodes to 0 the FEM incidence table is deleted..

It is even easier to import node coordinates via the Windows clipboard. For example, if the x-/y-coordinates of the FEM mesh nodes are available in an Excel table, it is possible to copy the two columns containing the data into the clipboard ("Edit/Copy") and then to paste them into the dialog box "Via a table" by pressing "Import clipboard".

• "Via equation"
  If you have entered the coordinates using the wrong scale, for instance, you can correct this using this menu item.

You have the option of applying the factor for one direction only. Activate the required option buttons.

• "In section"
  If the coordinates are to be altered for nodes in a specific area only, the area can be specified after selecting this button and the displacement of the nodes in the x- and/or y-directions then be entered in a dialog box. By activating the "Do not displace nodes with boundary conditions" check box the nodes concerned can be excluded from any displacement.
