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 -1.0 degrees
*************************************************************
** Factor of safety calculation for surface # 6184 **
** failed to converge within FIFTY iterations **
** **
** The last calculated value of the FOS was 21.9243 **
** This will be ignored for final summary of results **
*************************************************************
Circular surface (FOS= 21.9243) is defined by: xcenter = 285.52
ycenter = 293.10 Init. Pt. = 239.88 Seg. Length = 8.00

Factors of safety have been calculated by the
