4.0 ft line segments define each trial failure surface.
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 :_ (slope angle - 5.0) degrees

Negative effective stresses were calculated at the base of a slice.
This warning is usually reported for cases where slices have low self
weight and a relatively high "c" shear strength parameter. In such
cases, this effect can only be eliminated by reducing the "c" value.
USER SELECTED option to maintain strength greater than zero
