Airflow simulation around aircrafts, engines, buildings …

The CFD team (Computational Fluid Dynamics) is the biggest one at CERFACS. It focuses on flow simulation while developing advanced numerical methods applied to planes, rockets, helicopters, car engines, turbines, etc. The CFD team is strongly tied to other teams like GLOBC or PAE that also use CFD to forecast climate changes or the environmental impact of aviation: indeed, behind these themes, the equations that govern fluid flows are to be found first.

Calculate this engine before building it !

The CFD team develops essential tools in numerous applicative fields with a today well-known leitmotiv in the industrial world: let's calculate systems (planes, engines) before building them. This allows to reduce the cost of testing by one order of magnitude.  The CFD team is at the centre of this research along with its shareholders.

CFD is also a field where High Performance Computing is to be found : CFD simulations rely on fine computational grids with billions of points running on million-core supercomputers. Performing reliable and efficient calculations is another main focus for which Cerfacs is recognized as a key partner.

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
