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.

NOTE: Minimum Block Volume can have implications on removability of adjacent blocks, and therefore overall stability of the slope. The idea with setting a Minimum Block Volume is so that:
  1. Small blocks (e.g., grain of sand, pebble) cannot act as key blocks or blocks which prevent subsequent removal or failure of adjacent blocks.
  2. 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.
