Spencer-Wright Method of Analysis - Circular Failure Surface
------------------------------------------------------------
Critical Failure Surface Search using Multiple Circle Generation Techniques
Initial failure surface approximation - Factor of Safety: 2.633 Final Angle of Interslice Forces
(Theta) : 10.2 degrees
Analysis Summary
There were: 18665 successful analyses from a total of 20001 trial failure surfaces (Theta filter applied)
9 analyses that failed to produce a valid result
1327 analyses rejected due to Theta being outside valid range
Critical (minimum) Factor of Safety: 1.85 Final Angle of Interslice Forces: 11.0
degrees
Results Summary - Lowest 99 Factor of Safety circles
