DFN - Discrete Fracture Network

DFN apps refers to two main apps: DFN Generator and DFN Block Analyser. In order to have necessary inputs, the Rock Mass Data suite is needed, as well as the Ground Support Designer app. See the figure below to understand the workflow better.

• DFN Inputs and data gathering

Apps

Block Analyser

📄

Tools for probabilistic assessment of tetrahedral block formation on your excavation geometry, the stability of those formed blocks, and the performance of your ground support standards for supporting those blocks under static conditions.

DFN (Generator)

📄

This app allows you to generate DFN parameters from your structural data and calibrate the DFN parameters with your sampling data.
