GGU-STABILITY: Define centre-points (Ex. 2)
As the system input is complete, you must now describe the geometry of the slip circles. First, you have to define the centre-points. For this, the following menu items of the "Centre-points" menu are provided:
"Define in quadrilateral"
You click on the four corners of a quadrilateral with the mouse. You can then select an array subdivision. The centre-points will be set in accordance with the size of the quadrilateral."In rectangle"
You click on two diametrically opposed points of a rectangle and enter an array subdivision. The centre-points will be set in accordance with the size of the rectangle."Individually (graphically)"
You define the coordinates of individual centre-points by clicking with the left mouse button."Individually (editor)"
You enter the centre-point coordinates directly using the keyboard.
A current array can be supplemented and refined at any time. You can also swap between the described methods above. A total of 5000 slip circle centre-points can be entered.
The area above the slope which is clickable with the mouse is somewhat small. Select the "Zoom" menu item from the "Page size + margins" menu. Confirm the default zoom factor of 0.8 with "OK". Now select the "Individually (graphically)" menu item from the "Centre-points" menu and then click on some centre-points in front of the slope with the left mouse button. It is now up to you to try using one of the other methods for centre-point definition.
