Installing Nektar++ on OS X through MacPorts or Homebrew

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 […]
Direct numerical simulation of laminar-turbulent transition

Direct numerical simulation of laminar-turbulent transition

The process of laminar-turbulent transition consists of three stages: receptivity, linear eigenmode growth and nonlinear breakdown to turbulence. At the second stage, the interaction between Tollmien–Schlichting waves and base flow distorted by localised roughness elements generally prompts the onset of laminar-turbulent transition. For a small localised roughness element, the interaction has been addressed in our JFM paper. Recently, […]

An adaptable parallel algorithm for the direct numerical simulation of incompressible turbulent flows using a Fourier spectral/hp element method and MPI virtual topologies DOI: 10.1016/j.cpc.2016.04.011
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.
