When you are on Ares, you should ideally find the openfoam application already installed as a module. To see if there is an openfoam module in ares run the below command:

module spider openfoam
#module -r spider '.*openfoam*.'

To load the module use. (Note that this loads the default openfoam version)

module load openfoam

You can view the openfoam in list of provided packages in spack using:

spack list openfoam

To list the details of openfoam(version, description, dependencies, etc.)

spack info openfoam

spack install openfoam^adios2

Building from source

You can download the source and the documentation as a tarball

mkdir OpenFOAM
cd OpenFOAM
wget https://dl.openfoam.com/source/v2306/OpenFOAM-v2306.tgz
tar xzvf OpenFOAM-v2306.tgz

Now change the directory to the OpenFOAM distribution directory that just got uncompressed

cd OpenFOAM-v2306/

Prior to building, ensure that the system requirements are satisfied and source the correct OpenFOAM environment. For example, for the OpenFOAM-v2306 version:

source ~/OpenFOAM/OpenFOAM-v2306/etc/bashrc

There are the necessary minimum system requirements for installing OpenFOAM

gcc : 7.5.0
cmake: 3.8

You can check your versions using:

gcc --version
cmake --version
