The 7th annual Nektar++ Workshop will bring together developers and users of all experiences to hear about new and future developments in the Nektar++ spectral/hp element framework and the exciting science and engineering being undertaken with the code. The three days will include a comprehensive programme of talks and a poster session. The workshop will be run […]
The latest version of Nektar++, v5.3.0, was released on the 25th March 2023. This release includes a range of new features and improvements over the 5.2.0 release. A full list of the changes is available in the CHANGELOG.md file distributed with the source code. As always, if you encounter any problems please feel free to […]

The Nektar++ team recently gave an online seminar as part of the Computer Physics Communications seminar series.
In this post we will explain how to compile and run Nektar++ on the JUWELS supercomputer. The JUWELS supercomputer consists of two modules, the cluster module and the booster module. The booster module contains Nvidia GPU accelerators, and is not going to be covered in this post. Instead, we will focus on the booster module, […]
For complex geometries, we can use Solidworks to build the CAD model and use star-ccm+ for mesh generation. This blog gives a step-by-step instruction on the mesh generation of a round-tip wing.
Ansys ICEM CFD is a popular mesh generation software. In this blog, we show how to convert the mesh generated by ICEM to Nektar++ format.
In applications Pointwise (or the predecessor Gridgen) is a popular mesh generation software. In this post we go through the procedures to convert the linear mesh generated by Pointwise/Gridgen to arbitrary high order mesh for the solvers in Nektar++. The mesh conversion takes advantage of the already implemmented Gmsh interface in Nektar++. Assume we have […]
The visualisation of the flow fields output by Nektar++ may not look smooth if the resolution is not enough. A feasible solution is interpolating the spectral element field to a finite difference grid and then doing the post-processing using a Gaussian filter.
