Overview

code_saturne is the free, open-source multi-purpose software developed primarily by EDF for computational fluid dynamics (CFD) applications. It mainly solves the Navier-Stokes equations with scalar transport for 2D, 2D-axisymmetric, and 3D flows, whether steady or unsteady, laminar or turbulent, incompressible or weakly compressible, isothermal or not, using the Finite Volume Method (FVM) approach. A new discretisation based on the Compatible Discrete Operator (CDO) approach can be used for some other physics. A highly parallel coupling library (Parallel Locator Exchange - PLE) is also available in the distribution to couple other software with different physics, such as for conjugate heat transfer and structural mechanics. For the incompressible solver, the pressure is solved using an integrated Algebraic Multi-Grid algorithm and the velocity components/scalars are computed by conjugate gradient methods or Gauss-Seidel/Jacobi/Krylov solvers.

Building version 8.2.0

The version 8.2.0 of Code_Saturne is to be found here.

A simple installer InstallHPC.sh is made available for this version of the code and for HPC machines, where the GUI should not be installed. On a local machine, where the GUI would be used, the option --disable-gui should be deleted from the script.

This version assumes that the following modules are loaded:

module load intel/2024.0 compiler mkl hpcx/2.19
module load python/3.10

Tasks and Submissions

1. Run the application on 4 CPU nodes and submit the results

2. Run MPI Profiler to profile the application, which 3 MPI calls are mostly used? present your work in the teams interview ppt slides

3. Visualize the results, create a short video that demonstrate the given input via paraview or any other tool.

4. <TBD>

5. <TBD> …
