Training sessions at CERFACS - October 2015

5-9 Oct. 2015 - Numerical methods for Large Eddy Simulation

This training session allows participants to understand the underlying basics of Large Eddy Simulation (LES): numerics, boundary conditions, LES closures and combustion modeling. The CFD code AVBP (version 6.2) co-developed by CERFACS and IFPEN is used for hands-on to compute both academic and realistic configurations of reacting compressible flows.

12-14 Oct. 2015 Saclay, France - openpalm-meso : Formation MdS - Cerfacs - Equip@Meso : Couplage de codes avec OpenPALM

The OpenPALM coupler co-developed by ONERA and CERFACS has many features, and its use requires a dedicated training for physicists, computer scientists and developers of coupled applications. The purpose of the course is to learn to use PrePALM, the GUI of OpenPALM in order to quickly become autonomous on the instrumentation of the codes to couple as well as to use the various features of the coupler. The course is intended to be pragmatic with many hands-on activities. CERFACS engineers involved in its development teach this course.

15 Oct. 2015 - Versioning systems: introduction to GIT

GIT is a distributed revision control and source code management system. It was initially designed for Linux kernel development and is particularly adapted to multi-site and multi-developer environments. In the morning, the basic knowledge of source code managements are taught, presenting most GIT functionalities with many illustrations. A brief comparison with other management tools (Mercurial, CVS, SVN) is also proposed. In the afternoon, a hands-on session with detailed exercices is organized to illustrate the main concepts.

16 Oct. 2015 - Mesh generation using CENTAUR

Computational Fluid Dynamics in realistic geometries requires somplex meshes. This training course deals with the basics of unstructured and hybrid meshing using the Centaursoft software.

19 Oct. 2015 - Modal analysis of thermoacoustic instabilities using the AVSP solver

This training session aims at learning the participants the basics of combustion instabilities as well as how to use the thermoacoustic code AVSP developed at CERFACS. The latter is a general purpose Helmholtz solver which computes the frequency of oscillation, growth rate and spatial structure of the thermoacoutic modes of interest. Several test cases are considered during this one day training session in order to get the participants acquainted with the different features of AVSP (speed of sound inhomogeneities, complex valued boundary impedance, multi-perforated liners, acoustic flame coupling, multi-burner annular combustors,...).

DATA ASSIMILATION
9-12 March 2015

Data assimilation has become an important component of modelling for a growing number of applications in the geosciences and in engineering. This training course will provide an overview of the theory and practical methods of data assimilation. First the basic concepts from statistical estimation theory and nonlinear optimization will be given. The classical variational and Kalman filtering approaches to data assimilation will then be described. The lectures will also cover more specialized topics including covariance modelling and estimation, advanced minimization algorithms, preconditioning, and hybrid ensemble-variational methods. The lectures on the theory will be complemented by both practical exercises and presentations on specific applications at Cerfacs in the geosciences (oceanography, atmospheric chemistry and hydrology/hydraulics).

CLIMATE SCENARIOS DOWNSCALING METHODS
17-18 March 2015

There is a strong need in high resolution climate scenarios in France. Given that global climate models produce data at horizontal resolutions ranging from 100 to 200 km, their data output is not suitable for direct use in climate change impact studies at the regional and local scales. Hence, methodologies have been developed to downscale the output of large-scale climate models, such as dynamical or statistical methodologies. One such method has been developed at Cerfacs, the open-source software DSCLIM, a methodology that uses large-scale circulation information from global climate models, and links it to local-scale climate variables using a weather-typing based statistical model. Also, within the FP7 European project SPECS, an open-source R-based downscaling package is being developed. This training course aims to provide scientific and technical knowledge about downscaling methodologies, with hands-on t raining on DSCLIM output analysis.

COMPUTER ARCHITECTURES AND OPTIMISATION
20 March 2015

In this training course, the architectures of today's supercomputers are described. The processor evolution as well as the main types of architectures are then presented. Finally, the methods and tools for code optimization on these supercomputers are described.

NUMERICAL METHODS FOR NON-REACTING LARGE EDDY SIMULATION
30 March-3 April 2015

This training session allows participants to understand the underlying basics of Large Eddy Simulation (LES): numerics, boundary conditions, LES closures and combustion modeling. The CFD code AVBP (new version V7.0) co-developed by Cerfacs and IFPEN is used for hands-on to compute both academic and realistic configurations of reacting compressible flows.

20 janvier 2014 - Un nouveau projet du CERFACS  parmi les projets retenus dans la campagne INCITE 2014

Le programme INCITE vient d'annoncer que le CERFACS avait reçu une nouvelle allocation de 86 millions d'heures pour 2014 pour calculer la propagation de flammes turbulentes dans des batiments lors d'explosions accidentelles. Grâce au support de TOTAL, le CERFACS dispose aujourd'hui d'une base de données expérimentale unique sur ces thèmes puisque trois expérimentations exactement similaires en géométrie mais à des échelles 1, 6 et 24 ont été réalisées en Australie et en Norvége. Ces résultats expérimentaux combinés à la puissance de calcul disponible sur la machine INCITE (un BG/Q IBM) vont permettre de tester les modèles sur une gamme de paramètres jamais testée jusqu'ici. Le CERFACS est un des très rares groupes de recherche au monde ayant des allocations de temps CPU à la fois dans PRACE et INCITE.
