Discrete Fracture Network Modelling with DFN.lab

Course overview:

This two-day course focuses on modelling of fractured rock using the Discrete Fracture Network (DFN) approach and its implementation in the DFN.lab software.

The course begins with an introduction to methods for determining DFN structural parameters from field data.  The approach includes an overview of stereological methods, statistical analysis, and methods for analysing consistency between data of different types (borehole or map) and scales. Participants will then learn how to generate 3D DFN from deterministic and statistical data. The aim of the first day is to develop a site model in DFN.lab with stochastic DFNs and deterministic features such as major faults, boreholes, tunnels.

The second day of the course presents all the necessary steps to simulate flow and transport in the DFN. This includes assigning boundary conditions and transmissivities, running meshing methods, calculating flow using implemented numerical methods, and simulating transport using particle walkers.



A set of observation methods for fractured environments: boreholes, surface outcrops, or deep tunnels. These methods are used to build a DFN model and perform flow and transport simulations.
