GGU-SLAB: Step 2: Define the FEM mesh (Example 1)

A quadrilateral system is used. Mesh generation is simplest using the menu item "FEM mesh/Array".

Press the "Regular" button first and then the "Quadrilateral" button.

Enter the data as given in the dialog box. Activate the "Delete current nodes" check box. The immoveable left and right system boundaries can be defined in the above dialog box by activating the "Right" and "Left" check boxes. If all of the check boxes are deactivated (= all boundaries are assigned a free-earth support), define the immovable boundaries in Step 5.

The slab is displayed. Go to the menu item "Page size + margins/Auto-resize" in order to achieve a screen-filling representation of the system.
