Blog: The wake passing effect in LPTs with Nektar++

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 […]

Implementation of high-performance GPU kernels in Nektar++

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 […]

PyFR Tutorial Day 2020 (18th June 2020)

The PyFR Tutorial Day 2020 comprised step-by-step walk-throughs of several test cases, including scale-resolving CFD simulations in parallel on multiple GPUs. An overview of the PyFR codebase was also given, as well as deep-dive sessions into specific topics of interest. We are grateful to Amazon Web Services for providing access to multiple EC2 instances, each […]

Participation in the first global, virtual TRANSFORM!

The first global, virtual TRANSFORM took place in September 2020 (TRANSFORM 2020: Schedule). The Software Underground brought lots of interesting and useful sessions on the digital subsurface. This event was a bit different from most conferences: the sessions were fully participatory and interactive. Rhodri Nelson from Imperial College London gave a tutorial on “Geophysical Modeling […]
