CEA | 26 NOV 2015

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

Multiscale and multiphysics coupling needs

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

IN-VESSEL RETENTION WITH NEPTUNE_CFD

Context: In-vessel retention (IVR) of molten corium, ULPU-V experiments

Evaluate NEPTUNE_CFD capabilities with ULPU-V facility experiments

IN-VESSEL RETENTION WITH NEPTUNE_CFD


Computation domain used

for mesh refinement sensitivity

(made with SALOME)

Variation of void fraction in the fluid

domain (NEPTUNE CFD),

maximum heat flux.

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

Improve scalability and model capability on an industrial case



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
