He gives a talk on the entitled "Augmented Lagrangian preconditioner for linear stability analysis of incompressible fluid flows".

The efficient iterative resolution of saddle-point problem arising when addressing the stability analysis of incompressible flows is addressed using a class of preconditioner, the so-called  Augmented Lagrangian preconditioner. It has been implemented with the FreeFem++ software, in a parallel computing environment, thanks to an interface with the PETSc library, developed by P. Jolivet.

Jean-Lou Pfister presented his doctoral thesis at the PhD student's days organized by the scientific head of Material and Structures.

Olivier Marquet and Luis Henrique Benetti Ramos visit for two days Angelo Iollo and Michel Bergmann, members of the MEMPHIS team in INRIA Bordeaux. We discuss about the PhD project of Luis, who just joined the AEROFLEX team and will supervised by Angelo Iollo, professor at Bordeaux University. 

Tristan Leclercq, Departement of Mechanics, LadHyx-CNRS, Ecole Polytechnique, gives a seminar on "Drag reduction by elastic reconfiguration with dynamics"   
organized by the Department of Aerodynamics, Aeroelacticity and Acoustics of ONERA in Meudon.

The slides of the talk are available here.

Pierre Jolivet visited the AEROFLEX team in ONERA/Meudon, to discuss about new functionalities to add in the interface between the FreeFem++ software and the Petsc/Slepc libraries. These functionalities are required for implementing efficient preconditionners for computing fluid-structure instabilities

Jean-Lou, Johann and Luis presented their work at the PhD student's days organized by the scientific head of Energetic and Fluid Mechanics.

The manuscript "Flow-induced instabilities of springs-mounted plates in viscous flows: a global stability approach"

has been accepted for publication in Physics of Fluids. Even better, it is promoted as an Editor's Pick.

Luis published his first paper in Journal of Fluid Mechanics on the "Fluid-solid Floquet stability analysis of self-propelled heaving foils"

I am happy to annouce that our collaboration with Monash University is fruitful. The following manuscript has recently been accepted for publication in International Journal of Heat and Fluid Flow.
