OpenFOAM-Documentation

Installation and Regression Testing of OpenFOAM

OpenFOAM is a C++ toolbox for the development of customized numerical solvers, and pre-/post-processing utilities for the solution of continuum mechanics problems, most prominently including computational fluid dynamics (CFD).

Scope It is used in research organizations, academic institutes and across many types of industries, for example, automotive, manufacturing, process engineering and environmental engineering.

Purpose The goals of this project are 1) to install recent versions of OpenFOAM on the Uni.lu HPC platform using EasyBuild, and 2) to set up a regression testing configuration for the installed OpenFOAM using ReFrame.

** Running Test Examples for Post Processing Phase**

Verification and Validation Example with OpenFOAM v2312

Loading required modules

module load tools/EasyBuild/4.9.1
module use ~/.local/easyconfig/modules/all
module use /work/projects/mhpc-softenv/easybuild/aion-epyc-prod-2023a/modules/all/
export EASYBUILD_JOB_BACKEND='Slurm'
export EASYBUILD_PREFIX=$HOME/easybuild
export EASYBUILD_BUILDPATH=/dev/shm/$USER
eb /home/users/$USER/.local/easybuild/software/EasyBuild/4.9.1/easybuild/easyconfigs/o/OpenFOAM/OpenFOAM-v2312-foss-2023a.eb --job --job-cores 32 --job-max-walltime 11 --robot --trace
module use /home/users/$USER/easybuild/modules/all
module load cae/OpenFOAM/v2312-foss-2023a

Now, we're gonna supposed to download tutorials of openfoam v2312, then upload them in openfoam directory that we have created for motorbike example:

wget https://develop.openfoam.com/Development/openfoam/-/archive/OpenFOAM-v2312/openfoam-OpenFOAM-v2312.zip?     path=tutorials/incompressible/simpleFoam -O openfoam-OpenFOAM-v2312-tutorials-incompressible-simpleFoam.zip
mkdir -p $HOME/OpenFOAM
scp openfoam-OpenFOAM-v2312-tutorials-incompressible-simpleFoam.zip $HOME/OpenFOAM
unzip $HOME/OpenFOAM/openfoam-OpenFOAM-v2312-tutorials-incompressible-simpleFoam.zip -d $HOME/OpenFOAM
cd $HOME/OpenFOAM/openfoam-OpenFOAM-v2312/tutorials/verificationAndValidation/turbulenceModels/planeChannel

Source the OpenFOAM Environment Setup

source /home/users/$USER/easybuild/software/OpenFOAM/v2312-foss-2023a/OpenFOAM-v2312/etc/bashrc

Verifying the Environment Variable

echo $WM_PROJECT_DIR

Execution and running

chmod +x Allrun
srun -n 1 -c 32 ./Allrun
./Allrun
