Uncertainty quantification: theory and application to algorithms, CFD and geosciences

nasri |  

Deadline for registration: 15 days before the starting date of each training
Duration : 2 days / (14 hours)




This training course is given by three specialists of uncertainty quantification: Dr Pietro Marco Congedo – researcher at INRIA Bordeaux Sud-Ouest, Dr Vivien Mallet – researcher at INRIA Paris Rocquencourt, and Dr Pierre Sagaut – professor at Laboratory M2P2, Aix-Marseille University. The first half of the course focuses on theoretical aspects: uncertainties definition, Monte Carlo methods, projection methods, approximation methods and calibration data methods. The second half of the course is dedicated to application of uncertainty quantification to the fields of algorithm, CFD and geosciences.

Target participants

This training session is for engineers, physicists, computer scientists
and numerical analysts who wish to learn about uncertainty quantification.

Combustion research to be presented at the May 9th workshop of the French Académie des Sciences:

During the May 9th workshop organized at Académie des Sciences, combustion will be one of the topics discussed to illustrate the workshop topic ("Frontier Simulations in Solid and Fluid Mechanics"). The talk will be given by Dr T. Poinsot and will present recent progress in the field of LES of combustion, obtained at CERFACS in collaboration with CNRS laboratories, SAFRAN and ONERA. The full program is available here. At the same meeting, Pr F. Nicoud (CERFACS consultant) will also discuss recent work on blood flows performed in his group in Montpellier.Read more

CERFACS is partner in the “Chaire ANR industrielle” POSEIDON, inaugurated january 27th at Ecole Polytechnique

superadmin |  14 March 2017

POSEIDON, one of the 5 « Chaires ANR industrielles » selected in 2016, is interested in « New plasma thrusters for satellites in low Earth orbit ». Coordinated by Anne Bourdon from the Laboratoire de Physique des Plasmas, this project gathers Ecole Polytechnique, CNRS and Safran Aircraft Engines in view of developing a new experimental and numerical methodology allowing to reduce the number of tests required for the development of future Hall effect thrusters. CERFACS brings its expertise for the 3D simulation of such thrusters with their real geometry. Crédit Ph. Auvray, LPPRead more
