Code Saturne


The ARCHER2 Service is not yet available. This documentation is in development.

Code_Saturne solves the Navier-Stokes equations for 2D, 2D-axisymmetric and 3D flows, steady or unsteady, laminar or turbulent, incompressible or weakly dilatable, isothermal or not, with scalar transport if required. Several turbulence models are available, from Reynolds-averaged models to large-eddy simulation (LES) models. In addition, a number of specific physical models are also available as “modules”: gas, coal and heavy-fuel oil combustion, semi-transparent radiative transfer, particle-tracking with Lagrangian modeling, Joule effect, electrics arcs, weakly compressible flows, atmospheric flows, rotor/stator interaction for hydraulic machines.

Using Code Saturne on ARCHER2

Code Saturne is freely available to all users on ARCHER2.


The exact version information and module job-name is pending.

Running parallel Code Saturne jobs

Ccde Saturne can exploit multiple nodes on ARCHER2 and will generally be run in exclusive mode.

For example, the following script will run a Code Saturne job using 4 nodes (128x4 cores).


The following SLURM script requires validation


# Request 4 nodes with 128 MPI tasks per node for 20 minutes
# Replace [budget code] below with your account code,
# e.g. '--account=t01'

#SBATCH --job-name=CodeSaturne
#SBATCH --nodes=4
#SBATCH --tasks-per-node=128
#SBATCH --cpus-per-task=1
#SBATCH --time=00:20:00

#SBATCH --account=[budget code]

# Load the Code Saturne mdoule and run

module load code-saturne

code_saturne run --param case.xml
