Variable Restraints
-------------------
Parameter descriptor: XC YC R
Range of variation: 50.00 50.00 50.00
Trial positions within range: 50 50 50

RESULTS: Analysis 2 - Lab Scenario 5 pt2
Bishop Simplified Method of Analysis -Circular Failure Surface
---------------------------------------------------------------
Critical Failure Circle Search using Multiple Circle Generation Techniques
Factor of Safety for initial failure circle approximation: 2.88
There were: 63763 successful analyses from a total of 125001 trial circles
61238 analyses terminated due to unacceptable geometry
Critical (minimum) Factor of Safety: 2.87
Negative normal stresses exist on the base of one or more slices - examine slice data and consult the GALENA Help utility
Test Factor is less than 0.2 lower limit for one or more slices -examine slice data and consult the GALENA Help utility
