Block Generator Parameters
Feature Preservation: High, Medium Low
The options are the same as the ones used in Divide All and Re-Triangulate functions:
- High: Strict detail preservation, regardless of quality (e.g. can preserve near degenerate, sliver triangles)
- Medium: The processed geometry may lose some details as it attempts to reduce the amount of bad triangles
- Low: Re-triangulate with little constraints, which can result in obvious alteration, usually for simplifying geometry
Merge Tolerance
The option is the same as the one used in Divide All. User
defines the tolerance for merging the volumes of the geometry. Set the
value <=0 for the program to automatically set the tolerance.
Otherwise, any value >0, the user-defined tolerance will be applied
to merge the geometry. The unit of the tolerance volume is consistent
with the defined units in project settings.
Minimum Block Volume
Blocks with volumes smaller than the threshold are ignored in the post-processing after Compute Blocks during Compute Kinematics.
- Small blocks (e.g., grain of sand, pebble) cannot act as key blocks or blocks which prevent subsequent removal or failure of adjacent blocks.
- Small blocks are not computed by the kinematic engine to save on time and computing resources. It is assumed that such small-scale failures are inconsequential.
Pre-compute Bolt Snap Tolerance
Due to cumulative computing precision errors, bolt head locations may no longer be within tolerance to the slope surface geometry by the time bolts need to take effect in the Compute Kinematics stage. Even if the user has already applied Snap Imported Bolts during model construction, a secondary bolt snapping mechanism is required at the Compute Kinematics stage to account for machine precision and to ensure all bolts are fully intersecting the slope.
The pre-compute bolt snap tolerance is expressed as a percentage of the bolt length between the values of 0% and up to and including 100%. A bolt would snap to the slope surface if its head location were found within this user-defined tolerance. The method of snapping is by intersection, which means the snapping motion is along the bolt direction.
