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.

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.

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.
