GOLEM is a numerical simulator for modelling coupled Thermo-Hydro-Mechanical processes in faulted geothermal reservoirs. The simulator is developed by Antoine Jacquey ORCID iD iconGitHub icon id and Mauro Cacace ORCID iD iconGitHub icon id at the GFZ German Research Centre for Geosciences from the section Basin Modelling.

GOLEM is a MOOSE-based application. Visit the MOOSE framework page for more information.

Getting Started

Minimum System Requirements

The following system requirements are from the MOOSE framework (see Getting Started for more information):

  • Compiler: C++11 Compliant GCC 4.8.4, Clang 3.4.0, Intel20130607
  • Python 2.7+
  • Memory: 16 GBs (debug builds)
  • Processor: 64-bit x86
  • Disk: 30 GBs
  • OS: UNIX compatible (OS X, most flavors of Linux)

1. Setting Up a MOOSE Installation

To install GOLEM, you need first to have a working and up-to-date installation of the MOOSE framework.
To do so, please visit the Getting Started page of the MOOSE framework and follow the instructions. If you encounter difficulties at this step, you can ask for help on the MOOSE-users Google group.

2. Clone GOLEM

GOLEM can be cloned directly from GitHub using Git. In the following, we refer to the directory projects which you created during the MOOSE installation (by default ~/projects):

cd ~/projects
git clone https://github.com/ajacquey/Golem.git
cd ~/projects/golem
git checkout master

Note: the "master" branch of GOLEM is the "stable" branch which is updated only if all tests are passing.

3. Compile GOLEM

You can compile GOLEM by following these instructions:

cd ~/projects/golem
make -j4

4. Test GOLEM

To make sure that everything was installed properly, you can run the tests suite of GOLEM:

cd ~/projects/golem
./run_tests -j2

If all the tests passed, then your installation is working properly. You can now use the GOLEM simulator!


To run GOLEM from the command line with multiple processors, use the following command:

mpiexec -n <nprocs> ~/projects/golem/golem-opt -i <input-file>

Where <nprocs> is the number of processors you want to use and <input-file> is the path to your input file (extension .i).

Information about the structure of the GOLEM input files can be found in the documentation (link to follow).
