Nektar++ on the UCL Thomas cluster

Basic info about Thomas Thomas is the UK National Tier 2 High Performance Computing Hub in Materials and Molecular Modelling. Job submission is done using qsub. Jobscripts must begin #!/bin/bash -l in order to run as a login shell and get your login environment and modules. On Thomas, users do not submit directly to queues – […]

Direct numerical simulations of flow around wavy wings

Nektar++ has been used to investigate the incompressible flow around wings with spanwise waviness, using direct numerical simulations at different Reynolds numbers. The waviness was imposed by a coordinate transformation, using a novel technique presented in our JCP paper (1). This global mapping allowed us to consider a 2.5D problem, leading to significant advantages in terms […]

Nektar++ Workshop 2017

Nektar++ Workshop 2017
The Nektar++ Workshop 2017 will be held at Imperial College on 14th-15th June 2017. The 3rd annual Nektar++ Workshop will bring together developers and users of all experiences to hear about new and future developments in Nektar++ and the exciting science and engineering being undertaken with the code.

Contributing to Nektar++

Contributing to Nektar++
We encourage people who extend the code to help with their research to contribute those changes back into the main codebase for the benefit of other researchers. We have a number of tools and processes to help this including a code repository, a testing framework, code review and a continuous integration system.

Installing Nektar++ on OS X through MacPorts or Homebrew

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 versions of Nektar++.
