The series comprises invited talks on a range of topics related to the theory of high-order Flux Reconstruction schemes, their implementation in the PyFR (www.pyfr.org) flow solver, and their application to industrially relevant flow problems. The overarching objective of the series is to help bridge the gap between academic research activities and real-world industrial requirements. […]

The ARCHER2 national supercomputer is a world class advanced computing resource and is the successor to ARCHER. This guide is intended to provide basic instructions for compiling the Nektar++ stable release or master branch on the ARCHER2 system. Compilation instructions are available here: Nektar++ on ARCHER2 – Nektar++

The latest version of Nektar++, v5.0.1, was released on the 21st January 2021. It can be downloaded from the downloads page.

In this workshop we wish to share experiences on application of time-stepping techniques, for example parallel time integration, encapsulation of time integration and implicit time integration. As before the format of the on-line workshop will involve a series of 3 short 15-minutes talks followed by a group discussions and a summary session. The event’s programme […]

Congratulations to PRISM’s Principal Investigator Prof. Spencer Sherwin (Imperial College London) for being awarded a 2020 ECCOMAS Prandtl medal.  The Prandtl Medal is awarded for outstanding and sustained contributions to the area of computational fluid dynamics. ECCOMAS, the European Community on Computational Methods in Applied Sciences, is a scientific organization grouping together European associations with interests […]

In a gas turbine engine, the pressure expansion through the high- and low-pressure turbines (LPT) is achieved in a number of subsequent stages. The interaction of multiple stages of rotors and stators is a crucial source of deterministic unsteadiness which has repercussions on the loss production mechanisms, and it is thus of great importance to […]

Great work by Rini Banerjee, a student of Joint Mathematics and Computer Science at Imperial College London who spent summer 2020 doing a remote research internship on the Devito Project, under the supervision of Prof Paul Kelly and Dr Gerard Gorman. Rini has been working on the Devito Book: a set of Jupyter Notebook tutorials that […]

Implementation of high-performance GPU kernels in Nektar++ Due to the recent evolution of high performance computing hardware from single-core central processing units (CPUs) to multi-core CPUs and the emergence of general purpose graphics processing units (GPGPUs or short GPUs), these shared memory systems are now characterised by a high degree of parallelism. They also possess […]

Date: Wed, 30 September 2020, 14:00 – 16:00 Summary: Beyond CFD: In this workshop we wish to share experiences on application of PDE solvers which go beyond CFD tools, for example composable solvers, stability analysis, inverse problems, data assimilation and uncertainty quantification. The format of the on-line workshop will involve a series of 3 short […]

Research Software Engineering and PRISM  Photo by Glenn Carstens-Peters on Unsplash  The PRISM platform is characterised by its group of advanced scientific research software and the teams that build and maintain this software. Software engineering expertise is therefore a significant part of PRISM. The term Research Software Engineering or RSE is becoming increasingly common within the research community. Indeed, the […]
