Nektar++ on the Mira Cluster

Mira is a Blue Gene/Q supercomputer ran by the Argonne national laboratory. As of 2016, it is ranked as the fifth-fastest supercomputer in the world. If you are interested in using Nektar++ on Mira, please read on. Users of Mira often have access to Cetus, a smaller cluster with the same architecture as Mira. The […]

NekMesh: An open-source high-order mesh generation frameworkNovember 14, 2023
DOI: 10.2139/ssrn.4632754
We present NekMesh: an open-source mesh generation package which is designed to enable the generation of valid, high-quality curvilinear meshes of complex, three-dimensional geometries for performing high-order simulations.
Three-dimensional transition and forcecharacteristics of low-Reynolds-number flowspast a plunging airfoilAugust 31, 2023
DOI: 10.1017/jfm.2023.735
The three-dimensional (3-D) transition of the leading-edge vortex (LEV) and the force characteristics of the plunging airfoil are investigated in the chord-based Strouhal number Stc range of 0.10 to 1.0 by means of experimental measurements, numerical simulations and linear stability analysis in order to understand the spanwise instabilities and the effects on the force.
