Get the DuMuX adapter

Get DuMuX and preCICE, and build the adapter with dunecontrol.

The DuMuX-preCICE adapter is a DUNE module named dumux-precice which can be build using the DUNE build system. The DUNE build system is build on top of CMake and comes with various tools that make installation and management of DUNE modules easier. Therefore, it is recommended to install dumux-precice using dunecontrol. Please check out the DUNE installation instructions to get an overview over the dunecontrol tools and how DUNE modules work.

Prerequisites

DuMuX >= 3.7
- Builds using the current master branch of DuMuX might fail.
- If you run into trouble with a new DuMuX release, please open an issue in the repository and add the error message that you receive.
- Needs UMFPack (available via SuiteSparse) as solver for linear systems of equations. This is needed to run the examples included in the adapter. Otherwise you can skip UMFPack.
preCICE >=3.0.0
- The adapter is build via the DUNE build system that is based on CMake. Thus, the CMake link instructions for preCICE apply.
wget or git to download the DuMuX-preCICE adapter.
Optional: dune-subgrid allows for modified grid geometries.

The DuMuX-preCICE adapter should build fine if DuMuX, preCICE and their dependencies are installed.

Get DuMuX

Install DuMuX and the needed dependencies. The easiest way is to follow DuMuX’s installation instructions. The DuMuX project provides a script that installs and DuMuX and the DUNE modules required by DuMuX. This means, after installing DuMuX via the provided script you should be good to go to use the DuMuX-preCICE adapter.

After the installation you should have a root directory that contains the base DUNE modules, i.e. a number of directories named like dune-common, dune-geometry etc., and a directory called dumux.

Note that extended features of DuMuX or the DuMuX-preCICE adapter may need additional DUNE modules.

Get the adapter source

Download the DuMuX-preCICE adapter to the same directory as the DUNE modules and the dumux folder. It is recommended to use the latest release of the adapter, which can be found by checking out the relevant release tag.

git clone -b v2.0.0 https://github.com/precice/dumux-adapter.git

You can also try to clone the repository via SSH:

git clone -b v2.0.0 git@github.com:precice/dumux-adapter.git

Build the adapter

Before you build the adapter, verify that the dumux-adapter folder is in the same directory as the DUNE module folders and the dumux folder.

Build and configure the adapter using dunecontrol. While being in the directory mentioned in the previous step via calling

./dune-common/bin/dunecontrol --only=dumux-precice all

After the build and configure step a new directory build-cmake was created inside the dumux-adapter directory.

You can configure the build and configuration process using advanced options by manipulating CMake variables. dunecontrol allows to pass an options file for that

./dune-common/bin/dunecontrol --opts=OPTSFILE.opts --only=dumux-precice all

There is an opts-file provided by the adapter that resides in test/. You can use it as

./dune-common/bin/dunecontrol --opts=dumux-precice/test/cmake-test.opts --only=dumux-precice all

This provided cmake-test.opts file turns off some system-dependent optimizations such that the tests create comparable results on different computers.

To use the adapter in a separate DUNE module, we recommend building the adapter as a shared library. To do so, use the CMake option -DBUILD_SHARED_LIBS=ON to build the adapter and upstream modules. The DuMux install script uses dumux/cmake.opts, which already sets this option. Note that to change this setting it may be required to clear the CMake caches in build-cmake/CMakeCache.txt.

For more ways to manipulate/adapt the build and configuration step, please consult the dunecontrol documentation.

Important: In case you want to get both the DUNE adapter and the DuMux adapter, add all modules in the same directory, and use dunecontrol to build all modules. To ensure consistency among DUNE module versions, you might want to explicitly download and build each module, instead of using the installdumux.py script. Finally, make sure that you build all modules with the same CMake options (use the same --opts for both, or ommit it to use the default CMake options from vanilla DUNE).

Build tests (optional)

Optional, but recommended: Build all tests to verify the installation. For this navigate in the build-cmake/ directory and build the build_tests target.

cd dumux-adapter/build-cmake
make -j1 build_tests

You may speed up the build process by using more than one build job, e.g., use make -j4 in order to build with for processes at the same time.

Afterwards you can run the tests from the build-cmake directory using

ctest

If any tests fails, you should verify if something went wrong with the installation.

There are advanced ways of managing DUNE modules, e.g. using the environment variable DUNE_CONTROL_PATH, that are beyond the scope of this short documentation. You can find more information in the DUNE FAQ.
