Climate modeling and Global change (GLOBC)

Simulating the climate system dynamics

CERFACS conducts fundamental and applied research in the field of climate modeling and its global change. The “Climate modelling and global change” team (GLOBC) participates in the development of coupled models between the oceans, the atmosphere and the other components of the climate system. Numerical simulation of the evolution of these systems requires the use of high performance computers in order to correctly represent sufficiently fine spatial and temporal scales to reproduce the dynamics of the observed climate. Many simulations are carried out through various research projects and the analysis of the results leads to numerous publications in international journals. The DECLIPP challenge details a research strategy focuses on climate variability on decadal time scales.

To develop high level softwares

The team strategy is based on a dual approach combining theoretical modeling studies and on the development of high-level softwares, such as, for instance,  the   OASIS and OpenPALM couplers, needed to address the various linkages involved in climate science or in multi-physical / multi-component industrial applications.

To contribute to transverse axes

In continuation of this theme,   hydrology and hydraulics are leading areas of research, largely oriented towards the calculation of  uncertainties and  data assimilation. These activities contribute, in collaboration with other teams at Cerfacs,  to the MODEST challenge. All this research takes place through the coordination and participation in national and international research programs.

For many years, the team is associated with the National Centre for Scientific Research (CNRS) through the UMR CECI 5318 research unit.

The AVBP code from CERFACS at the heart of for PRACE projects from the 23rd call

CERFACS |  30 September 2021

Cerfacs is involved in three PRACE projects of the 23rd call for which hour allocation runs from 01/10/2021 to 30/09/2022. Researchers from ECL/LMFA UMR5509 (Ecole Centrale de Lyon) and IMFT (UMR 5502) laboratories have earned projects entirely based on the use of the LES solver developed by Cerfacs AVBP and involve the support of experts from the CFD and COOP teams underling the importance and effectiveness of collaborations between French labs and Cerfacs. Alexis Giauque from ECL/LMFA UMR5509 (Ecole Centrale de Lyon) has obtained not only one but two PRACE projects! The first project LESFAN (RA0101, 30 000 000 CPU hours on Irene/Rome TGCC) is based on the use of AVBP in the turbomachinery version to study the generation of noise by a fan of a real airplane engine. The second, PRACE-EDGES (RA0101, 40 000 000 CPU hours on Irene/Rome TGCC) focuses on LES modeling of dens gas in complex geometries. To do so, the LMFA Team has developed advanced thermodynamic closures in AVBP allowing the direct simulation of such flows. Laurent Selle from IMFT (UMR 5502) has received CPU hours for the GASTON project (RA0061, 30 000 000 CPU hours on Marenostrum BSC) which aims to study the structure of hydrogen flames in porous materials. For this, IMFT and Cerfacs will perform coupled simulations considering the reactive flow with AVBP as well as the conduction in the porous medium with AVTP which is known to play an central role in the flame stabilization process. Carlos Perez Arroyo from IMFT (UMR 5502) received 16 Mh CPU hours on Joliot-Curie Skylake partition to support his project WONDER.Read more
