67 climate modelling groups use OASIS3-MCT to assemble more than 80 coupled applications
10 September 2019
OASIS3-MCT is a coupler of codes developed at Cerfacs and used around the world, mainly for climate modelling applications. Our last survey confirms that OASIS3-MCT is used by 67 modelling groups to assemble more than 80 different coupled applications over the 5 continents. These applications include global or regional configurations of ocean and atmosphere models but also sea ice, sea level, wave, ocean biogeochemistry, land, vegetation, river routing, hydrological and atmospheric chemistry models. OASIS3-MCT is used in 5 of the 7 European Earth System Models participating to the 6th Coupled Model Intercomparison Project (CMIP6) that produces the climate simulations forming the basis of the next report of the Intergovernmental Panel on Climate Change (IPCC)”

The changing risk of extreme precipitation is difficult to project. Events are rare by definition and return periods of heavy precipitation events are often calculated assuming a stationary climate. Furthermore, ensembles of climate model projections are not large enough to fully categorize the tails of the distribution. We propose a clustering algorithm to identify self‐similar hydroclimates to estimate changes in the expected frequency of extremely rare events under scenarios of global mean temperature change. We find that, although there is some regional variation, record events are projected in general to become more intense, with 500 year events intensifying by 10‐50% under 2°C of warming and by 40‐100% under 4°C of warming.
IMFT and CERFACS win a second ERC (European Research Council) advanced grant in combustion !
3 April 2019
The latest results of the 2018 ERC have been announced: IMFT (Institut de Mécanique des Fluides de Toulouse) and CERFACS have won a second ERC advanced grant in the field of combustion: . This 2.5 Meuro grant will allow to study hydrogen combustion for the storage of renewable energies using experiments (at IMFT) and simulations (using CERFACS tools). This is the second ERC advanced grant obtained by IMFT and CERFACS after the INTECOCIS project in 2013 (intecocis.inp-toulouse.fr) and it confirms the unique place of Toulouse in the world of combustion.

8 March 2019
Each year, the Academy recruits new members in order to enlarge or enhance its scope of reflection and action, this being carried out within a rigorous recruitment process which focuses on people's excellence and on the visibility of their works in Europe and worldwide. On 5 December 2018, the plenary assembly proceeded with the election of 16 new members which brings the number of Academicians to 330. Among its new members : Catherine LAMBERT, manager of CERFACS and Stéphane ANDRIEUX, Scientific Chief Executive of ONERA.
The Combustion Institute Selection Committee has selected Dr Laurent GICQUEL to receive the honorific title of Fellow of the Combustion Institute in 2018
5 March 2019
The Combustion Institute Selection Committee has selected Dr Laurent GICQUEL to receive the honorific title of Fellow of the Combustion Institute in 2018 for outstanding research in LES of turbulent reacting flow and thermo-acoustic instability prediction of real engines. Fellows of The Combustion Institute are members of the international combustion community recognized by their peers as distinguished for outstanding contributions to combustion, whether it be in research or in applications. Fellows are active participants in The Combustion Institute, as evidenced by the publishing of papers in CI affiliated journals, attendance at the International Symposia on Combustion, and/or attendance at CI Section meetings.

CERFACS is participating in the Allons-y à vélo initiative!
16 January 2019
CERFACS is participating in the Allons-y à vélo initiative! (AYAV) The next edition will take place from 21 to 25 January. Let's go by bike means leaving your car in the garage, working on your legs and getting some fresh air! By promoting the use of bicycles as a means of daily commuting to and from work, CERFACS affirms, alongside 2 pieds 2 roues association, its willingness to participate in the effort to protect the environment. Actions in support of biking at CERFACS, such as the IKV (Indemnité Kilométrique Vélo), are listed on the CERFACS website along with activities organised as part of AYAV. Like CERFACS, Go by bike !
Cerfacs rewarded by two prices at the Safran Aircraft Engines R&T day – 17 December 2018
19 December 2018
On Dec 17th, Cerfacs participated to the R&T Safran Aircraft Engines day during which Safran AE and their partners presented their research and development work. Cerfacs research was presented on various posters providing a general overview of numerical simulation activities performed with Safran in the fields of combustion chamber, compressor, turbine and numerical methods. Five CERFACS Phd student (CIFRE) also presented their work in 180 seconds. Over the 6 prices attributed to Safran AE partners, Cerfacs was awarded by the contract agility price. This price was awarded for the partner delivering fast responses to consultations and allowing quick and easy contract setup. Finally, Félix Collin-Bastiani received a prize for his Phd research on modeling and simulation with large eddy simulation of ignition processes in two-phase flow and real-world conditions.
