     The medium 3D lid-driven cavity benchmark with 200^3 cells and the 
     small HPC_motorbike case with ~8 Million cells, are configured in:

     ---------------------------------------------------------------------

Please source the openfoam environment, e.g.: source <your-path-to>/OpenFOAM-v2106/etc/bashrc.
Also please verify that the PETSc libraries can be loaded properly. Run the following commands:
     eval \$(foamEtcFile -sh -config petsc -- -force)
     foamHasLibrary -verbose petscFoam

Then go the the benchmark tests at the location described above and run the respective scripts:
1. bench-lid-driven-cavity  | This is used to run the 3D Lid-driven cavity benchmark
2. bench-hpc-motorbike      | This is used to run the HPC-motirbike benchmark"
