Minimum Surfaces

The Minimum Surfaces are the lowest safety factor surfaces, for a given analysis method, generated at each grid point of a slip center grid.

The Minimum Surfaces option is only applicable when a Grid Search for circular surfaces has been performed, using a slip center grid. It is not applicable for non-circular surfaces.

The display of Minimum Surfaces can be toggled ON or OFF, by selecting the Minimum Surfaces option from the toolbar or the Data menu.
