DFN.lab
A software platform for DFN modelling
“Fractures matter”
DFN.lab is a modular computational suite to deal with three-dimensional Discrete Fracture Network (DFN) models from generation to simulation and analysis of connectivity, flow, mechanical and transport properties. Core modules are developed in C++ for high performances and a Python API is provided for easy use.
