DFN Files

As objects in the model, discrete fracture networks, or DFNs, are described in detail in the Discrete Fracture Network (DFN) topic.

Inclusion in a Model

DFNs are created either using c fracture commands or imported using the fracture import command, which accepts a file or a geometry as the basis for creating a new DFN in the model.

Formats

The program supports import of DFNs from itasca, fishlab, or fracman formats. The itasca format is the default, and is described in DFN-Related File Formats.
