Nektar++ on ARCHER

The ​ARCHER national supercomputer is intended for very large-scale computations and is the successor to ​HECToR. These instructions are preliminary in nature and an up-to-date version of the master branch is required as support for the compilation environment has only been added recently.

A Guide to the Implementation of Boundary Conditions in Compact High-Order Methods for Compressible Aerodynamics

DOI: 10.2514/6.2014-2923
The nature of boundary conditions, and how they are implemented, can have a significant impact on the stability and accuracy of a Computational Fluid Dynamics (CFD) solver. The objective of this paper is to assess how different boundary conditions impact the performance of compact discontinuous high-order spectral element methods (such as the discontinuous Galerkin method and the Flux Reconstruction approach), when these schemes are used to solve the Euler and compressible Navier-Stokes equations on unstructured grids.

Nektar++ on IDRIS (France)

The following is the script used to configure Nektar++ 3.4 on IDRIS (large HPC cluster in France). This script must be lauched from a directory containing nektar++-3.4.0.tar.gz and ThirdParty-3.4.0.tar.gz. ThirdParty In order to build ThirdParty-3.4.0.tar.gz, follow these steps from an internet-enabled computer: Nektar++ Then do the following:
