ANGULAR RESTRICTIONS
---------------------
The first segment of each failure surface will be
inclined
within the angular range defined by
Lower angular limit -45.0 degrees
Upper angular limit -5.0 degrees
Factors of safety have been calculated by the

The most critical circular failure surface
is specified by 12 coordinate points
