DuMux is a module for simulation of multi-phase multi-component flow transport in porous media

What is DuMu^x?

DuMu^x is a simulation toolbox mainly aimed at flow and transport processes in porous media. DuMu^x is based on the DUNE 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. Have a look at our publications (see below: How to cite) for a more detailed description of the goals and motivations behind DuMu^x.

Installation

Have a look at the installation guide or use the DuMu^x handbook, Chapter 2.

Automated Testing

• DuMu^x 3.3 / Dune 2.7:
• DuMu^x master / Dune 2.7:
• DuMu^x master / Dune master:

DuMu^x features many tests (some unit tests and test problems) that can be run manually. We have experimental support for automated testing with buildbot. Click here (buildbot) to see the latest builds (clicking on a build number will show a detailed overview of the build).

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.

Contributing

Contributions are highly welcome. Please ask questions over the mailing list. Please review the contribution guidelines before opening issues and merge requests. For bug reports contact us over the mailing list, or file an issue. For bug fixes, feature implementations open a merge request or send us formatted patches.

Backwards Compatibility

For a detailed description of the backwards compatibility policy, please see contribution guidelines.

DuMu^x releases are split into major(e.g. 2.0, 3.0) and minor (e.g. 3.1, 3.2, 3.3) releases. Major releases are not required to maintain backwards compatibility (see below), but would provide a detailed guide on how to update dependent modules. For each minor release, maintaining backwards compatibility is strongly encouraged and recommended.

Despite the goal of maintaining backwards compatibility across minor releases, for more complicated changes, this is decided upon on a case to case basis, due to limited developer resources. In the case that implementing full backwards compatibility for an update is not feasible, or would require unreasonable resources, the degree of backwards compatibility be decided by a vote in one of the monthly core developer meetings.

Major version update, 2.12 to 3.0

With the version update to version 3, many features have been added and a lot has been improved in DuMu^x. See the changelog for a list of changes. If you decide to update from version 2.12, please have a look at our small guide on how to update an application to the new version.
