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 […]

Nektar++ on the Imperial College HPC cluster

Imperial College’s HPC system contains computing resources suitable for a broad range of jobs. Node sizes and interconnects therefore vary. This cluster is useful for serial runs, small and large parallel runs, parameter sweep studies, etc. There are also some dedicated private queues which some users may have access.
