Abstract

Antares is a Python data processing library developed at CERFACS to help engineers and researchers to read, manipulate, and analyse simulation data. The library can read a wide range of result formats such as AVBP, CODA, CGNS, ProLB, Tecplot, and many other, handling both structured and unstructured steady and unsteady simulations. Antares has been adopted by many of our industrial and academic partners such as Airbus and Safran due to the large number of general and domain specific post-treatment algorithms.

• Geometry manipulation: cuts, clips, iso-surface, line-extraction, etc.
• Numeric computation: gradients, integrals, interpolation, normal vectors, etc.
• Signal processing: DFT, POD, SPOD, DMD, radial and azimuthal decomposition, etc
• Turbomachinery: thermodynamic averages, blade and profile unwrapping, Cp computation, etc.
• Aeroacoustics: Acoustic power, Ffowcs Williams-Hawkings analogy, Goldstein analogy, acoustic imaging.
• Visualization: 1D and 3D plots.
• Others: boundary layer characterisation, chorochronic reconstruction, and many more.

Objective of the training

This training aims to introduce Antares, and to provide participants with the practical skills and tools to incorporate the library into a post-processing workflow.

Learning outcomes

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

• • Install ANTARES
  • Understand the core concepts of the library: Base, Readers, Writers and Treatments
  • Read and write data from different CFD codes
  • Use Antares treatments for data analysis and visualisation
  • Find and navigate the Antares documentation
  • Integrate Antares into a complex post-processing workflow

Teaching methods

The training is an alternation of theoretical and practical courses. 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 Montilla

Target participants

This training session is intended for students, researchers, and engineers who wish to learn how to use Antares to process numerical data from their simulations.

Fee

Prerequisites and registration
