AnDFN, Analytical Discrete Fracture Network

Introduction

AnDFN is a computer program for the modelling of groundwater flow in a discrete fracture network (DFN). The program is based on the Analytic Element Method (AEM) and is distributed as a Python package with various modules and scripts.

The documentation for AnDFN is available here.

Installation

AnDFN can be installed from PyPi.

Installation:

pip install andfn

Update:

pip install andfn --upgrade

Uninstall

pip uninstall andfn

Dependencies

andfn has the following required dependencies:

numpy
pandas
scipy
pyvista
numba
h5py

and the following optional dependencies:

pyyaml (for using the YAML configuration file)
matplotlib (for some optional plots)

Functionality

AnDFN currently have the following functionality:

Generate random DFN
Compute the intersections of a DFN
Solve the AEM model for a DFN
Plot the flow net for the AEM model
Import DFNs
Load and save DFNs

Getting started

A template for a simple AnDFN model and several examples are available in the examples folder (under development).
