Contour Blocks

The Contour Blocks feature is a heatmap that shows the areas of the slope which have blocks of the highest/lowest computed values.
The availability of Contour Data depends on the analysis mode. In a Deterministic Analysis, the computed values for each block are unique, whereas for a Probabilistic Analysis, computed values for each block may vary between different sample runs. Therefore, in a Probabilistic Analysis, only critical values are reported.

In a Deterministic Analysis, the following data is available:

• Factor of Safety
• Weight
• Volume
• Driving Force
• Resisting Force
• Required Support Pressure
• Failure Depth
• Slope Face Area
• Failure Iteration

In a Probabilistic Analysis, the following data is available:

• Min. Factor of Safety - minimum factor of safety for all sample runs of a given block
• Max. Weight - maximum block weight for all sample runs of a given block
  
• Max. Require Support Pressure - maximum required support pressure for all sample runs of a given block
• Max. Failed Depth - maximum failed depth for all sample runs of a given block
  
• Probability of Failure - sum of all failed samples (FS < Design FS) / total samples for the given block

The blocks contoured can be for All Valid Blocks or for a subset of blocks which only encompass Removable Blocks or Failed Blocks. See the Results Set topic for more information.
