What is DuMuX?
===============

[DuMuX][0] is a simulation toolbox mainly aimed at flow and transport
processes in porous media. DuMuX is based on the [DUNE][1]
framework and aims to provide a multitude of numerical models as well
as flexible discretization methods for complex non-linear phenomena,
such as CO2 sequestration, soil remediation, drug delivery in cancer
therapy and more. See [our publication][2] for a more detailed
description of the goals and motivations behind DuMuX.


Installation
===============

Have a look at the [installation guide][3] or use the [DuMuX handbook][4],
Chapter 2.

Automated Testing
==================
[![buildbot badge](https://git.iws.uni-stuttgart.de/buildbot/badges/dumux-master-dune-latest-gcc.svg)](https://git.iws.uni-stuttgart.de/buildbot/#/builders)

DuMuX features many tests (some unit tests and test problems) that can
be run manually. We have experimental support for automated testing with buildbot.
Click <a href="https://git.iws.uni-stuttgart.de/buildbot/#/builders" target="_blank">here (buildbot)</a>
to see the latest builds (clicking on a build
number will show a detailed overview of the build).

[![coverage report](https://git.iws.uni-stuttgart.de/dumux-repositories/dumux-coverage/badges/master/coverage.svg)](https://pages.iws.uni-stuttgart.de/dumux-repositories/dumux-coverage/)

A weekly coverage report of the test suite is created by gcovr/gcov. The report
currently doesn't include non-instantiated code, so the real coverage is likely lower. However,
only a few lines of code are never instatiated in the comprehensive test suite.
