NEXTSIM AIMS TO INCREASE THE CAPABILITIES OF CURRENT COMPUTATIONAL FLUID DYNAMICS TOOLS FOR AERONAUTICAL DESIGN BY RE-ENGINEERING THEM FOR EXTREME-SCALE PARALLEL COMPUTING PLATFORMS.

NextSim project is focusing on the next-generation computational fluid dynamics tools for HPC environments

NextSim partners, as fundamental European players in Aeronautics and Simulation, recognise that there is a need to increase the capabilities of current Computational Fluid Dynamics tools for aeronautical design by re-engineering them for extreme-scale parallel computing platforms. The backbone of NextSim is centred on the fact that, today, the capabilities of leading-edge emerging HPC architectures are not fully exploited by industrial simulation tools. Current state-of-the-art industrial solvers do not take sufficient advantage of the immense capabilities of new hardware architectures, such as streaming processors or many-core platforms.

NextSim will focus on the development of the numerical flow solver CODA, that will be the new reference solver for aerodynamic applications inside AIRBUS group, having a significant impact in the aeronautical market.

To demonstrate NextSim market impact, AIRBUS has defined a series of market relevant problems. The numerical simulation of those problems is still a challenge for the aeronautical industry and their solution, at a required accuracy and an affordable computational cost. 

Three additional working areas are proposed in NextSim: algorithms for numerical efficiency, algorithms for data management and the efficiency implementation of those algorithms in the most advanced HPC platforms.

NextSim aims to increase the capabilities of current Computational Fluid Dynamics tools for aeronautical design by re-engineering them for extreme-scale parallel computing platforms.

Objectives

Aircraft design is a very competitive and demanding field. Achieving a highly optimised design, which permits the manufacturing of lighter, quieter, safer, and better performing aircraft with lower fuel consumption, is a very complex task that requires taking into account a large number of different disciplines (aerodynamics, structure, system, vibration, acoustic, etc.). An advanced, highly efficient and accurate design/optimisation toolset, acting as a virtual facility, which provides full information about the design status, and suitable to be applied in virtual certification, is the target of the European aircraft industry. What is needed is to be able to automatically predict flow physics, aircraft forces, radiated acoustics, stresses, evolution of the design status, and the optimal shape for any specified constraints. Moreover, such tools need to be extremely accurate, and it should be fast enough to run in realistic engineering design timescales.
