Scientific challenges at CERFACS

Research at CERFACS is performed on 9 cross-functional axes, from high performance computing and advanced algorithms (numerical methods, code coupling, data assimilation, uncertainties) to expanding themes such as climate, environment , combustion, aeronautics.

Its application fields deal with scientific challenges structuring several decadal projects. These challenges meet the cross-functionnal CERFACS research areas conducted  by one or several teams.

  • The Cougar and Puma challenges respectively aim at the simulation of the unsteady functioning of a complete engine of gas turbine and of a whole aircraft in realistic flight conditions.
  • The Declipp challenge deals with decadal prediction and climate variability using climate modeling and a coupled ocean-atmosphere model.
  • The Decola challenge is about simulating unsteady combustion of rocket engines in realistic “supercritical” named conditions.
  • The Modest challenge gathers specialized modeling activities about environment and security. This in order to better characterize natural and industrial risks in terms of monitoring, scenarios and real-time tracking.

More challenges may be created in consultation with the CERFACS shareholders.

NextSim General Assembly and TC meeting

CERFACS |  16 September 2021

The General Assembly and TC Meeting took place on 15-16 September 2021. CERFACS is involved in the NextSim project (). The primary objective is to increase the capabilities of Computational Fluid Dynamics tools on extreme-scale parallel computing platforms for aeronautical design. This project has received funding from the European High-Performance Computing Joint Undertaking (JU) under grant agreement N° 956104. The JU receives support from the European Union’s Horizon 2020 research and innovation programme and Spain, France, Germany. This project has received funding from the Agence Nationale de la Recherche (ANR) under grant agreement N° ANR-20-EHPC-0002-02. For more information, please visit Read more


Sophie Valcke from Cerfacs co-authored a new book on atmosphere-ocean modelling

CERFACS |  18 August 2021

new book "Atmosphere-Ocean Modelling - Couling and Couplers” by Prof. Carlos R Mechoso, Prof. Soon-Il An and Dr Sophie Valcke has just been published by World Scientific. The present book fills a void in the current literature by presenting a basic and yet rigorous treatment of how the models of the atmosphere and the ocean are put together into a coupled system. Details are available at  Abstract: Coupled atmosphere-ocean models are at the core of numerical climate models. There is an extraordinarily broad class of coupled atmosphere-ocean models ranging from sets of equations that can be solved analytically to highly detailed representations of Nature requiring the most advanced computers for execution. The models are applied to subjects including the conceptual understanding of Earth’s climate, predictions that support human activities in a variable climate, and projections aimed to prepare society for climate change. The present book fills a void in the current literature by presenting a basic and yet rigorous treatment of how the models of the atmosphere and the ocean are put together into a coupled system. The text of the book is divided into chapters organized according to complexity of the components that are coupled. Two full chapters are dedicated to current efforts on the development of generalist couplers and coupling methodologies all over the worldRead more
