This post briefly summarises how to install Nektar++ using either the MacPorts or Homebrew package managers. Both of these install a version of Nektar++ that includes MPI for parallel execution, ARPACK for stability analysis, FFTW for homogeneous expansions, PETSc support and a full set of solvers. They can also both be used to install development versions of Nektar++.
The process of laminar-turbulent transition consists of three stages: receptivity, linear eigenmode growth and nonlinear breakdown to turbulence. Recently, the interaction between Tollmien–Schlichting waves and base flow distorted by 3D localised roughness elements has also been studied.

Abstract: A hybrid parallelisation technique for distributed memory systems is investigated for a coupled Fourier-spectral/hp element discretisation of domains characterised by geometric homogeneity in one or more directions.
The ECMWF HPC facilities are composed by two identical Cray XC30 systems that support both operational forecast requirements of the centre and research.
Copper is a Cray XE6 system and supports research programs of the United the States Department of Defense (DoD). The system is provided for computationally based science and engineering and is intended for high performance computing, large-scale storage, and utility computing.
Nektar++ Workshop 2016
7th-8th June 2016
The purpose of this meeting is to bring together the Nektar++ developers and design team with users of any experience level within the broader community. More information is available here.
Members of PRISM community are delighted to invite you to Imperial College on Monday 18th April for an event that explores the use of accelerators with finite element methods. More information is available here.

This study addresses linear dispersion–diffusion analysis for the spectral/hp continuous Galerkin (CG) formulation in one dimension.
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 […]
