Mesh generation using CENTAUR

nasri |  

Cerfacs is Qualiopi certified for its training activities

Duration : 1 day (6,5 hours)

Satisfaction index

In November 2022, 70% of participants were satisfied or very satisfied

(results collected from 10 respondents out of 12 participants, a response rate of 83%)

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.

Referent teacher: Carlos Perez Arroyo

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

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.
