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…)

Satisfaction index

In November 2021, 100% of participants were satisfied or very satisfied

(results collected from 11 respondents out of 11 participants, a response rate of 100%)

 

Abstract

CFD in realistic geometries requires complex meshes. Among the many commercial knitters on the market, CENTAUR is particularly powerful for unstructured meshes. It is therefore a good candidate for meshing complex geometries.

Objective of the training

The objective of this training is to learn mesh generation techniques, especially for unstructured and hybrid meshes using the CENTAUR software.

Learning outcomes

At the end of the training, participants will be able to:

  • Use CENTAUR via the graphical interface.
  • Import a geometry, clean it and put in data the boundary conditions.
  • Create the sources of refinement, whether they are surfacic or volumic.
  • Generate a first mesh and have a critical look at the number of cells and smallest cell volume.
  • Evaluate the quality of the mesh and know how to clean it.

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 intended for anyone in the field of CFD (engineers, doctoral students, postdocs, trainees) wishing to mesh any geometry under Centaur. The target is primarily internal aerodynamics, not external (aircraft wing for example).

Prerequisites and registration

Basic knowledge of what a mesh is and preliminary notions of CFD.

In order to follow this course, you need to:

  • be familiar with the use of basic Linux commands
  • have level B2 of the CEFR because the training can take place in French or in English depending on the audience.

In order to verify that the prerequisites are satisfied, the following questionnaire 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 it.

Video presentation of the NextSim EuroHPC project

CERFACS |  14 December 2021

The video presentation of the NextSim project has just been released : 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
