Spencer-Wright Method of Analysis - Circular Failure Surface
------------------------------------------------------------
Critical Failure Surface Search using Multiple Circle Generation Techniques
Initial failure surface approximation - Factor of Safety: 4.891 Final Angle of Interslice Forces
(Theta) : 10.1 degrees
Analysis Summary
There were: 19859 successful analyses from a total of 20001 trial failure surfaces (Theta filter applied)
127 analyses that failed to produce a valid result
15 analyses rejected due to Theta being outside valid range
Critical (minimum) Factor of Safety: 3.47 Final Angle of Interslice Forces: 11.6
degrees
Results Summary - Lowest 99 Factor of Safety circles
