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.

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.

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.

A PhD student awarded of the “Outstanding Student Poster” of EGU

superadmin |  6 November 2019

Rem-Sophia MOURADI, PhD student at CERFACS  and EDF R&D Hydraulic Department, has been awarded of the "Outstanding Student Poster", during the EGU General Assembly 2019 (European Geosciences Union). This international conference gathers each year about 16 000 scientists with 6 000 oral presentations and 10 000 posters. Among the 2 500 posters presented by PhD students, fifty only are awarded with this price, that to say 2%.
