SALOME-CFD:
EDF’S REFERENCE
PLATFORM FOR CFD
SUMMARY
1. Why build a platform for CFD?
2. SALOME-CFD content and specificities
3. Some studies with SALOME
4. And tomorrow?
CONTEXT
Some actions around SALOME at MFEE
Test and use on industrial cases for CAD and MESHES Visualisation: remote and in situ viewing
Internal promotion of SALOME (training, new hires, trainees, …)
Education: use SALOME for CFD module (Ecole des Ponts ParisTech, ISUPFERE)
First CFDSTUDY module
Available since 2008, but built as a post install process
CONTEXT
Number of users increases
Develop a workbench for studies Simplifying installation process Increase usability
Optimize return time for studies
Use other SALOME modules (ADAO, OPENTURNS, HOMARD, …)
Remote viewing capability

SALOME-CFD PLATFORM
Specifities
2 platforms :
Open source: Code_Saturne + SYRTHES
Restricted: Code_Saturne + NEPTUNE_CFD + EOS (Equation Of State library) + SYRTHES Common content: GEOM, MESH, PARAVIS, MED, YACS, JOB MANAGER,
PARAMETRIC, HOMARD, HEXABLOCK, OPENTURNS, ADAO
2 modes for each solver (CFD): optimize and debug
Module CFD located on Code_Saturne for post install capabilities (SALOME-MECA) Build system based on YAMM
SALOME-CFD PLATFORM
Easy to build: just use YAMM Easy to install: just execute ".run"
Direct access to PORTHOS cluster for visualization

Computation domain used for mesh refinement sensitivity (made with SALOME)
Variation of void fraction in the fluid domain (NEPTUNE CFD),
FUEL BUNDLE WITH NEPTUNE_CFD
Simulate a fuel bundle (5x5) with NEPTUNE_CFD under accidental conditions
Geometry, inputs and measurement points provided by OECD/NEA: PSBT benchmark based on NUPEC PWR subchannel and bundle tests, possibility to publish results
FUEL BUNDLE WITH NEPTUNE_CFD
Bundle geometry: 5x5 rods array 4 meters long
7 mixing vane spacers 2 non mixing vane spacers 8 simple spacers
All meshes made with Salome 7.x TUI + GUI
Meshes:
mixing vane spacer: 19.2 million cells with MG tetra (GHS3D) non mixing vane spacer: 10.9 million cells with MG tetra (GHS3D) simple spacer: 4.8 million cells with MG tetra (GHS3D)
extrusion for bundle
for the bundle: 256 million cells test 680 millions and 17x17 mesh

SHORT AND LONG TERMS GOALS
Improved user experience Short term objectives:
Make all capabilities available in graphical mode (debug, coupling study, …) Simplify the use of CFD with Catalyst (in-situ visualization)
Increase number of tutorials (text and movies) Medium term objectives:
Increase links with other modules (ADAO, OPENTURNS, HOMARD, …) Build version with Code_Aster and CFD module
Long term objectives Windows version
