Access DFN.lab

DFN.lab logo

DFN.lab is a modular software suite for 3D Discrete Fracture Network (DFN) modeling, from statistical or genetic fracture generation to connectivity analysis, flow, transport, and mechanical simulations. The core is developed in C++ for performance, with a Python API for flexible scripting and integration.

Scientific References & Validation

DFN.lab builds on long-term research in fractured media hydro-mechanics. Key methodological developments and applications are documented in peer-reviewed publications.

See the full list on the DFN.lab main page – Publications section, including:

  • Le Goc et al. (2019) – DFN.lab platform presentation
  • Davy et al. (2018) – Elastic properties of fractured rocks, JGR Solid Earth
  • Multiple studies on flow, transport, upscaling, and hydro-mechanical behavior in fractured crystalline rocks

Users are encouraged to cite the relevant papers when using DFN.lab in publications.
