Couplers developed at CERFACS

Coupling

Coupling numerical models is a central issue in many research fields such as climate modelling, computational fluid dynamics, atmospheric chemistry, etc.

Ideally, a coupler, i.e., the software interface between the different models, should allow the realization of coupled simulations on different types of platforms at a minimal cost, the  testing of different coupling algorithms (e.g. time strategy or interpolation methods), or to change the numerical modeling components that participate in the coupled simulation in order to realize coupled model intercomparisons. Two couplers are developed at CERFACS: OASIS and OpenPalm.

OASIS

OASIS3-MCT coupling

OASIS3-MCT coupling

The OASIS coupler « Ocean Atmosphere Sea Ice Soil » is a software allowing synchronized exchanges of coupling information between numerical codes representing different components of the climate system.

OpenPalm

OpenPALM coupling

OpenPALM coupling

 

OpenPalm is a software allowing the concurrent execution and the intercommunication of programs based on in-house as well as commercial codes. For climate modelling an ocean model could be coupled with and atmospheric model through OpenPalm, for a combustion chamber temperature simulation a combustion model could be coupled with a radiation model…

Medal of the Academy of Air and Space: 3 CERFACS researchers awarded !

Brigitte Yzel |  11 July 2022

The Air and Space Academy awarded Carlos Pérez Arroyo, Gabriel Staffelbach and Jérôme Dombard with the Vermeil medal 2022, to honor the excellence of their work in the realization of the FULLEST project, the first high-fidelity simulation of an aircraft engine. Thanks to PRACE for awarding the access to the Joliot-Curie supercomputer (GENCI hosted at CEA/TGCC) and to DGAC for the funding of the ATOM project (No 2018-39) led by SAFRAN Tech. FULLEST also benefited from developments done in European projects:  EXCELLERAT (H2020 823691) and EPEEC (H2020 801051).  Read more


ROLAND GLOWINSKI CONFERENCE IN PARIS FROM JULY 5th to 7th
