The 9th annual Nektar++ Workshop will bring together developers and users of all experiences to hear about new and future developments in the Nektar++ spectral/hp element framework and the exciting science and engineering being undertaken with the code.
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.
The latest version of Nektar++, v5.7.0, was released on the 30th October 2024.
The ARCHER2 national supercomputer is a world class advanced computing resource and is the successor to ARCHER. This guide is intended to provide basic instructions for compiling the Nektar++ stable release or master branch on the ARCHER2 system.
This blog explains how to set up industrial simulations using the Incompressible Navier-Stokes (IncNS) Solver in Nektar++. The geometry here is the Imperial Front Wing (IFW), an unraced front-wing configuration of the McLaren MP4-17D race car. Combined with a rolling wheel, it is a representative model for modern open-wheel motorsports, especially Formula 1 front-wing designs.
HX1 (or Hex) is the new High Performance Computing Cluster provided by the Research Computing Services at Imperial College London. This post describes how to set up Nektar++ on HX1.
Taylor-Couette (TC) flow involves fluid motion between rotating concentric cylinders, one of the key problems in fluid dynamics. In this study, we aim to focus on the effects of ‘sinusoidal’ radial heating on the TC flow dynamics.
Underwater radiated noise from shipping activities and offshore wind turbine construction/operation acts as a stressor for marine mammals. Using Nektar’s high-order spectral element method the Acoustic Perturbation Equations were numerically solved to explore the complex physics of acoustic scattering and interference of acoustic waves.
The latest version of Nektar++, v5.5.0, was released on the 31st January 2024.
