GGU-STABILITY: "Contours" menu item

If you have read-in a pwp mesh or have defined a pwp mesh by hand, you can have lines of equal potential (contours) displayed using this menu item. It is also possible to have normal contours displayed or colour-filled contours. The dialog boxes which appear are described more closely in Section "Safety/Utilisation factors (slip circles)/Contours" menu item” and in Section "Safety/Utilisation factors (slip circles)/Coloured" menu item.
