Thematics / Mini-workshops

These mini-workshops may change and cover more or less topics. This page will be adapted according to your feedback.

Combustion - B. Cuenot, CERFACS

• H2 and alternative fuels combustion
• turbulent combustion modeling

Dynamic mesh adaptation - G. Balarac, LEGI

• anisotropic mesh adaptation
• adaptation criteria for anisotropic mesh adaptation
• adaptation of periodic domains

Multi-phase flows - V. Moureau, CORIA

• scalar transport in two-phase flows
• three-phase flows: contact angle

Numerics - G. Lartigue, CORIA

• implicit time integration for compressible/incompressible flows
• higher-order finite-volume schemes
• finite-volume schemes for anisotropic meshes

Turbulent flows - P. Bénard, CORIA

• turbulence injection
• wall modeling
• rotor modeling for wind or hydro turbines applications
• advanced post processing for unsteady turbulence

User experience - R. Mercier, SAFRAN TECH

• automation & workflows for HPC
• on-line and off-line analysis of massive datasets

Fluid structure interaction - S. Mendez, IMAG

This project gathered three sub-projects related to fluid-structure interactions (FSI). Their common feature was the FSI solver from YALES2, which is based on a partitioned approach. The FSI solver couples an Arbitrary Lagrangian-Eulerian solver for predicting the fluid motion in a moving domain (ALE) and a solver for structural dynamics (SMS), which are both YALES2 solvers. The FSI solver is quite recent and initiated by Thomas Fabbri (LEGI, Grenoble) and the object was to spread its use among several teams, with the objective to improve its performances, demonstrate its versatility and add multiphysics effects.

GENCI Hackathon - G. Staffelbach, CERFACS

• Porting to GPU with OpenACC
