ETP4HPC Webinar - Collaborative development of the Next-Generation Computation Fluid Dynamics Solver CODA by Onera, Airbus and DLR

11:00 am - noon CEST

The collaboration between academia, research centers and industry has become a key element to maintain the competitiveness of the European aerospace industry. Industrial needs and use cases can highlight open research topics and industrial partners can turn R&D outcome into innovations and products for the market, while research centers help bridging the gap between academia and industry for improving the research-technology transfer.

Such collaborations are however not always easy to set up and maintain over a long period. To address the need to fundamentally re-design CFD software and to make use of advanced HPC infrastructures, Airbus, ONERA and DLR decided in 2017 to jointly develop the new next generation CFD code CODA. This is the first joint CFD code development by the three partners with a focus on modern algorithms and on exploiting current and future HPC hardware architectures while making use of modern software engineering and code design in a collaborative way of working across organisations. The tools will enable the aerospace industry to solve problems currently out of reach within the constraints of balancing accuracy versus computational load. This will eventually result in improved CFD capabilities that can be employed when aiming to design aircraft that are lighter, quieter and more fuel-efficient which produce less greenhouse gas emissions.

This Webinar will address the background of the collaboration and its implementation, the status of the code and the perspective for establishing CODA as a European Next-Generation CFD, Analysis and Design Platform.

In this webinar, Airbus, ONERA and DLR will share some insight on their joint work, as well as on the content, but also on how they make it work – the difficulties they faced and the lessons they learned and are worth sharing. 

Agenda

• 11:00 Introduction and housekeeping (ETP4HPC office)
• 11:10 Airbus/Onera/DLR: what we do and how we make it work
• 11:40 Open Q&A session, chaired by Jean-Philippe Nominé and Sai Narasimhamurthy

Speakers

Vincent Couaillier (Onera)

• Head of the Research Unit “Numerical methods in Fluid Mechanics” in the Department “Aerodynamics, Aeroelasticity and Acoustics” of ONERA. The research unit is involved in innovative algorithm research and development for numerical methods in aerodynamics, aeroacoustics, and multidisciplinary coupling.
• Doctoral thesis at Sorbonne University on multigrid methods
• Involved since 35 years in R&D for CFD, including industrial application challenges with a particular focus to aircraft and turbo-engines turbulent flow simulations. The activity includes software development management (elsA, CODA, Aghora) used by industrial partners (mainly Airbus, Safran) based on structured and unstructured FV and DG methods for RANS and LES models. Supervising of PhD candidates.
• Involved since 25 years in several European projects for numerical methods in fluid mechanics including FV/DG methods and uncertainty propagation, bilateral cooperation with DLR and USAF, international CFD workshops.

Stefan Görtz (DLR)

Stefan Görtz earned his M.Sc. in Mechanical Engineering from TU Darmstadt, Germany, and his M.Sc. in Vehicle Engineering and his Ph.D. in Aeronautical Engineering from KTH, Sweden. He performed his post-doctoral research at the US Air Force Academy.

Stefan joined the German Aerospace Center (DLR) in 2006 and was appointed University Professor for Multidisciplinary Design Optimization by TU Braunschweig in December 2019. Until March 2020, he was the principle investigator of the DLR project VicToria, which was concerned with the implementation of DLR's roadmap for virtual design and certification of aircraft and helicopters. Since 2020, he is the head of the Center for Computer Applications in AeroSpace Science and Engineering (C²A²S²E) at the DLR Institute of Aerodynamics and Flow Technology in Braunschweig. The C²A²S²E department is engaged in the research, evaluation and deployment of advanced numerical methods and software solutions for multidisciplinary simulation and optimization of aircraft, including the development of the next generation flow solver CODA in collaboration with the French Aerospace Lab ONERA and Airbus. As the head of a cross-institute development team, he is also responsible for the implementation of DLR's guiding concept "the virtual product".
