The 9 March 2021

CFD data processing using Antares

Jean-François BOUSSUGE |  

Deadline for registration: 15 days before the starting date of each training
Duration : 1 day / (6,5 hours)

Before signing up, you may wish to report us any particular constraints  (schedules, health, unavailability…) 

at the following e-mail address : training@cerfacs.fr


Satisfaction index

In March 2019, 100% of participants were satisfied or very satisfied

(results collected from 13 respondents).



This training session aims at learning about the Antares library. This python tool enables to process numerical data from CFD simulations (and from other domains).
Using this library, users can develop their own programs that can read and write data in many formats, also compatible with many visualization standard tools, and that modify this data with available treatments.

Objective of the training

The simple software architecture and the python language allow the user to become the developer of its own features.

Learning outcomes

On completion of this course, you will be able to :

–  install the Antares python library,

–  to use the basic objects of the library in a python program,

–  to contribute to the improvement of development and to find help thanks to the Antares Redmine platform,

– find and use the Antares documentation to use the advanced functions of the library,

– implement the library in a complex application

Teaching methods

The training is an alternation of theoretical presentations and practical work. A multiple choice question allows the final evaluation. The training room is equipped with computers, the work can be done in sub-groups of two people.

Target participants

This course is for anyone wishing to process numerical data from CFD calculations in order to extract physical analysis.


  • Knowledge of Unix commands.
  • Basic knowledge of Python
  • Knowledge of the field of numerical simulation
  • The training can take place in French or English depending on the audience, level B2 of the CEFR is required.

In order to verify that the prerequisites are satisfied, the following questionnaires must be completed. You need to get at least 75% of correct answers in order to be authorized to follow this training session. If you don’t succeed it, your subscription will not be validated. You only have two chances to complete them.

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
