DFN Block Analyser

The DFN Block Analyser allows you to generate tetrahedral around underground excavations and to assess the probabilistic static ground support system performance.

Key Features

Generate tetrahedral from multiple DFN realisations around underground excavations
Paint on the excavation the frequency or weights of blocks generated
Use designed (regular tunnel, circular tunnel, or intersection) or survey excavations
Analyze ground support design (from the Ground Support Designer app) performance for static tetrahedral blocks
- 3D view
- View performance stats on each support element in profile
Ground support experiments - quick statistical comparison of performance with variations in bolt spacings and shotcrete coverage
Quantification of each DFN input parameter's (P32 and mean joint diameter) influence on the blocks generated using a particular joint set

Supported Data Types

DFN inputs
Imported DFN
Underground excavations: planned dimensions or surveys
