Research activities

Computational strategies for high performance computing:

• Proper Generalized Decomposition (PGD)
• Model reduction, approaches for parametrized problems
• Nonincremental strategy LATIN
• Time and space multiscale methods
• Multiphysics, coupled problems
• Domain decomposition, parallelism
• Nonlinear behavior, contact

Examples of applications:

• Fluid-structure interaction in porous media (coll. University of Padova, Italy)
• Virtual testing of the joints of Ariane 5 space launcher (project funded by CNES, coll. EADS-ASTRIUM-ST)
• Taking account of variability in engine blades (MAIA/SAFRAN project funded by ANR)
• Optimization of the geometry of car devices (OMD2/RENAULT project funded by ANR)
• Taking account of variability in fatigue simulations (APPROFI/SAFRAN project funded by ANR)
• New solutions of damping in Ariane 6 space launcher (ARIAN/AIRBUS-DS project funded by ANR)
• Simulation of fretting-fatigue (COGNAC project funded by SAFRAN)
• Model reduction for the simulation of damage in earthquake engineering (project funded by ANR and IRSN)
• Transfer of high-performance model reduction techniques to an industrial finite element code (project funded by SIEMENS)
