GGU-SLAB: Button "Regular"
The regular array allows the nodes to be defined in several ways:
"Line"- along one or more lines,
"Rectangle" - in one or more rectangles,
"Quadrilateral" - in one or more quadrilaterals.
The procedure is similar for all three cases. Therefore, only the rectangles will be described.
"Rectangle"

Enter the corner points of the array and the number of subdivisions. If the "Delete current nodes" check box is activated, all existing nodes are deleted and then the user-defined FEM nodes in the dialog box are generated with the appropriate FEM mesh. If you want to add further nodes, deactivate the check box.
You can define immovable boundaries directly when generating the FEM mesh. Just activate the check boxes for the required sides. If the check boxes are not activated, all boundaries are generated with a free-earth support. Additional displacement or action boundary conditions can then be defined individually using the "Boundary" menu.
If only one of the node points thus generated were to lie within an existing FEM mesh, node generation is aborted with an error message and no further nodes are generated.
