ECCOMAS MS088 – State-of-the-art Machine Learning Techniques For Computational Fluid Dynamics

Lisbon Congress Centre Praça das Indústrias 1, Lisboa, Portugal

Machine learning (ML) in scientific applications including computational fluid dynamics (CFD) is a growing field of research. However, ML can be less stable and more prone to errors in CFD because of its complexity relative to e.g. game theory. Thus, recent research has concentrated on reinforcement learning (RL) or physics-informed methods applied to CFD. Another continuously growing field of research which alleviates the common problems of ML in CFD is physics-informed neural networks (PINNs). Recently, modified versions of classical PINNs have been proposed to push their limitations and make them more tailored to CFD. With these considerations in mind, this minisymposium will discuss the applicability, predictive performance and limitations of state-of-the-art ML methods in CFD.

Introduction to Computational Fluid Dynamics

HLRS University of Stuttgart Nobelstraße 19, Stuttgart, Germany

Join our Anna Schwarz as one of the instructors for the reoccuring “Introduction to Computational Fluid Dynamics” course organized by HLRS, IAG (University of Stuttgart) and the
Institute of Software Methods for Product Virtualisation (DLR).

FLEXI/GALÆXI: Open-Source Solver for Multiscale Flows

Join us for the 11th CASTIEL Code of the Month to learn about FLEXI/GALÆXI!
Both solvers provide a high-order consistent simulation tool chain for solving the compressible Navier–Stokes equations in a highly efficient, accurate and robust manner in a high performance computing setting either on CPU-based systems (FLEXI) or GPUaccelerated clusters (GALÆXI).

Programming complex workflows with PyCOMPSs

Online

Programming large-scale systems poses several challenges to scientific application developers. Join us for a webinar on PyCOMPSs, a pioneering approach to task-based programming in Python that enables codes to be executed in distributed computing platforms. This webinar will give an overview of PyCOMPSs illustrated with examples in development at BSC that include CFD simulations with AI training or real-time visualization in the same workflow.

GALEXI: Scale-resolving simulations of compressible turbulence on GPU-accelerated systems

Room 9

Joine our Anna Schwarz for her talk “GALEXI: Scale-resolving simulations of compressible turbulence on GPU-accelerated systems”, part of the workshop “Tackling Software Exascale Challenges: the Centres of Excellence in High-Performance Computing Perspective”. She will present GALEXI, the GPU version of FLEXI, and the grogress she’s made in CEEC preparing these codes for exascale CFD simulations.
