Previously, there were a completely different check for UnstructuredGrid and CpGrid. The latter probably not working properly due to missing support in the DUNE grid interface. This commit resorts the code to use the UgGridHelpers abtraction instead of UnstructuredGrid's legacy grid interface. Thus one code can be used to do the checks for both grids. For UG the code compiles and the test is successful. For CpGrid it compiles but of course the test still fails due to missing transmissibility multiplier support. This will be sorted out in a different PR.
Open Porous Media Automatic Differentiation Library
CONTENT
opm-autodiff contains a small library for automatic differentiation built on the Eigen linear algebra package. It also contains some experimental solver and simulator prototypes demonstrating how it can be used. The most important parts are:
- AutoDiffBlock.hpp (class for AD on vectorized data with sparse jacobians)
- AutoDiffHelpers.hpp (various utilities to simplify writing solvers)
- sim_fibo_ad.cpp (prototype fully implicit black-oil simulator)
LICENSE
The library is distributed under the GNU General Public License, version 3 or later (GPLv3+).
PLATFORMS
The opm-autodiff module is designed to run on Linux platforms. It is also regularly run on Mac OS X. No efforts have been made to ensure that the code will compile and run on windows platforms.
REQUIREMENTS
opm-autodiff requires opm-core, and all its requirements (see opm-core/README). In addition, opm-autodiff requires Eigen, version 3.1 (has not been tested with later versions).
DOWNLOADING
For a read-only download: git clone git://github.com/OPM/opm-autodiff.git
If you want to contribute, fork OPM/opm-autodiff on github.
BUILDING
See build instructions in opm-core/README, or at http://opm-project.org/download.php.
DOCUMENTATION
Efforts have been made to document the code with Doxygen. In order to build the documentation, enter the command
make doc
in the topmost directory. The class AutoDiffBlock is the most important and most well-documented.
REPORTING ISSUES
Issues can be reported in the Git issue tracker online at:
https://github.com/OPM/opm-autodiff/issues
To help diagnose build errors, please provide a link to a build log together with the issue description.
You can capture such a log from the build using the `script' utility, e.g.:
LOGFILE=$(date +%Y%m%d-%H%M-)build.log ;
cmake -E cmake_echo_color --cyan --bold "Log file: $LOGFILE" ;
script -q $LOGFILE -c 'cmake ../opm-core -DCMAKE_BUILD_TYPE=Debug' &&
script -q $LOGFILE -a -c 'ionice nice make -j 4 -l 3' ||
cat CMakeCache.txt CMakeFiles/CMake*.log >> $LOGFILE
The resulting file can be uploaded to for instance gist.github.com.
