Open Porous Media Core Library

THIS MODULE IS DEPRECATED. The code is now integrated in the other modules.

These are release notes for opm-core.

CONTENT

opm-core is the core library within OPM and contains the following

• Fluid properties (basic PVT models and rock properties)
• Grid handling (cornerpoint grids, unstructured grid interface)
• Linear Algebra (interface to different linear solvers)
• Pressure solvers (various discretization schemes, flow models)
• Simulators (some basic examples of simulators based on sequential splitting schemes)
• Transport solvers (various discretization schemes, flow models)
• Flow diagnostics (time-of-flight and tracer solvers, diagnostic functions)
• Utilities (input and output processing, unit conversion)
• Wells (basic well handling)

LICENSE

The library is distributed under the GNU General Public License, version 3 or later (GPLv3+).

PLATFORMS

The opm-core 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.

sudo apt-get install python-software-properties

add this repository for necessary backports (required for Ubuntu Precise)

sudo add-apt-repository -y ppa:opm/ppa sudo apt-get update

parts of DUNE needed

sudo apt-get install libdune-common-dev libdune-istl-dev libdune-grid-dev

libraries necessary for OPM

sudo apt-get install -y libtinyxml-dev

Ensemble based Reservoir Tool Eclipse utilities module

IMPORTANT: if you install this (binary) version of ERT,

you will get the 2015.04 release version. That

is only compatible with the 2015.04 release version

of OPM! If you are building OPM from source you should

use the latest master branches of both ERT and OPM.

sudo apt-get install ert.ecl

Note: You should compile the OPM modules using the same toolchain that was used to build DUNE. Otherwise, you can get strange ABI errors.

DOWNLOADING

For a read-only download: git clone git://github.com/OPM/opm-core.git

If you want to contribute, fork OPM/opm-core on github.

BUILDING

There are two ways to build the opm-core library.

1. As a stand-alone library. In this setup we recommend creating an entirely separate directory outside the directory containing the source code and doing the build from that separate directory (termed "the build directory"). This configuration is sometimes referred to as an "out-of-source build".

As an example, consider the following layout in which "opm-core" refers to the directory containing the package source code as downloaded from GitHub

workspace
  |
  +-- build
  |
  +-- opm-core
  |     |
  |     +-- ...
  |     |
  |     +-- opm
  |     |
  |     +-- ...

We will configure a release-type (optimised) build using traditional Unix Makefiles within the "build" directory. The following command configures the build

cd path/to/build
cmake ../opm-core -DCMAKE_BUILD_TYPE=Release

If you want to debug the library you should specify the build type "Debug" instead of "Release" in the command above. This will disable optimizations and make it easier to step through the code.

Building the software then amounts to typing

make

in the top-level "build" directory; i.e., the directory from which we invoked the "cmake" utility. On a multi-core computer system you may want to build the software in parallel (make(1)'s "job-server" mode) in order to reduce the total amount of time needed to complete the build. To do so, replace the above "make" command with

make -j N

or, possibly,

nice -20 make -j N

in which "N" is an integer that should typically not exceed the number of cores in the system.

Once the library has been built, it can be installed in a central, system-wide location (often in "/usr/local") through the command

sudo make install

2. As a dune module.

• Put the opm-core directory in the same directory as the other dune modules to be built (e.g. dune-commmon, dune-grid). Note that for Ubuntu you can install Dune from the ppa as outlined above.
• Run dunecontrol as normal. For more information on the dune build system, see http://www.dune-project.org/doc/installation-notes.html

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.

REPORTING ISSUES

Issues can be reported in the Git issue tracker online at:

http://github.com/OPM/opm-core/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.
