Scaling Nektar++ to 65K CPUs on ARCHER2

The recent capability day on ARCHER2 allowed us to study the performance of the IncNavierStokesSolver in Nektar++ up to 65536 CPUs. We will discuss the strong scaling of the solver using the current best-practise configuration for an aerodynamic test case inspired by the Formula 1 industry. Best-practice for IncNavierStokesSolver We are using the best-practise setup […]

Synthetic turbulence generator in Nektar++November 12, 2024
Advancements in modern hardware and numerical methods have significantly enhanced the feasibility of scale-resolving simulations, such as direct numerical simulation, for industrial applications. For effective application, these simulations require the generation of realistic incoming turbulence to ensure accurate predictions of the flow field.
