GGU-2D-SSFLOW: Step 2: Define FEM nodes and mesh (Example 1)

The rough system structure consists of four boundary points and one point in the centre (well), so there are five points in all. The input of system points is therefore easiest using the menu item "Mesh/Change".

Select the "Via a table" button and the "0 FEM nodes to edit" button in the following dialog box. Enter 5 as the new number of FEM nodes and confirm the input. Then enter the five coordinate pairs in the table.

Now go to the "Mesh/Automatic" menu item and confirm all message boxes displayed. In order to achieve a screen-filling display click menu item "Page size + margins/Auto-resize" or simply press the [F9] function key.
