GGU-STABILITY: "ASCII file" menu item

You can read-in the coordinates (x, y) and the corresponding potentials (h) from an ASCII file created with a different program (e.g. GGU-2D-SSFLOW). Alternatively, you can save an existing pw mesh as an ASCII file by pressing the "Save" button in the dialog box.

After selecting the "Read" button and then a file, the following dialog box appears:

Open

The current line of the ASCII file is shown at the top of the window. Using the arrows at the right you can move through the file. If all input is correct, the result for this line will appear in the box below the columns. Otherwise, "Error" will appear. You may then have to alter the column delimiter. If the file contains invalid as well as valid lines, these will be simply skipped when reading. Finally, select the "Import data" button. You can then further process the read-in coordinates.

The coordinates and the potential alone do not supply the program with the necessary information. After loading an ASCII file, you must additionally specify how the individual nodes are linked to one another. Further explanations can be found in the other menu items of the "Pwp mesh" menu.
