Block Type and Results Set
There are two (2) Block Types in RocSlope3: Unit Blocks and Combined Blocks. Each Block Type has its own Results Sets for interpretation, where a Results Set consists of a subset of blocks.
| Block Type | Available Results Sets |
| Unit Blocks and Combined Blocks | All Valid Blocks |
| Unit Blocks | All Valid Blocks |
| Removable Blocks | |
| Failed Blocks | |
| Combined Blocks | Removable Blocks |
| Failed Blocks |
The different Results Sets are defined as follows:
- All Valid Blocks - a block is considered "valid" if it does not touch the non-terrain surface or intersect any search limits. This includes the entire collection of blocks being computed for the selected Block Type.
- Removable Blocks - valid blocks are considered "removable" if there exists at least one valid translating direction to geometrically remove the block out of its socket. This is a subset of All Valid Blocks.
- Failed Blocks (FS < Design FS) - valid and removable blocks are considered "failed" if its factor of safety is less than the Design Factor of Safety specified in Project Settings. This is a subset of Removable Blocks (since a block cannot possibly fail without being removable).
Combined Blocks determined via the largest removable algorithm are by definition valid and removable. Hence, Results Sets for Combined Blocks include just Removable Blocks and Failed Blocks, as All Valid Blocks are a duplicate of Removable Blocks.
The selected Block Type and Results Set affect:
- Block Colors: Only blocks belonging to the Results Set are coloured according to the Block Coloring mode (e.g., Random Colors, Active Contour). All other blocks are coloured according to the Material Property colours. If the selected Block Type is “Unit Blocks and Combined Blocks”, then Unit Blocks would be coloured while Combined Blocks would be outlined to avoid overlaps in visualization.
- Block Information: Only blocks belonging to the Results Set are listed. If the selected Block Type is “Unit Blocks and Combined Blocks”, then the Block Information would not list any entries.
Results Set acts like a filter, but unlike Edit Filter in Block Information, only block colour is affected, not its visibility.
Compute Blocks
After Compute Blocks, the All Valid Blocks Results Set is shown.
Compute Kinematics
After Compute Kinematics, the selected Results Set is shown. The default Results Set is Removable Blocks. The Results Set options can be located in either of two ways:
- Select: View > Display Options and select the Results
tab. - In the Visibility Tree, select the Results node to display the Results Set options in the Properties Pane.
Probabilistic Results Set
In a Probabilistic Analysis, the definitions of the Results Set is modified slightly since not all sample runs for a given block will results in the same Removable flag or Factor of Safety.
- All Valid Blocks - same definition as Deterministic Analysis.
- Removable Blocks - at least one sample run results in the block becoming "removable".
If Successive Failure is OFF, then this subset of blocks will be the same as a Deterministic Analysis (i.e., key blocks are not affected). If Successive Failure is ON, then the resulting Factor of Safety for each sample run can affect the removability of subsequent blocks beyond the key blocks.
- Failed Blocks (FS < Design FS) - at least one sample run results in the block having a FS < Design FS (failed).
