Research Assistant / Associate in High-order spectral/hp element methods

This role will support the application of computational modelling using exascale computing by assisting in the re-development of core algorithmic components of the Nektar++ spectral/hp element framework. This position will investigate the role of high-performance computing and exascale technology, in creating an efficient and flexible programming framework for high-order spectral element methods with a particular focus on compressible flow simulations

You will drive the programming and development of high-order spectral/hp element methods and solver technology, suitable for exascale platforms, that are required to meet a range of challenging problems in the aerospace and energy sectors. These will be implemented in the Nektar++ framework (www.nektar.info). You will also have the opportunity to engage with a number of world-leading partners through the Nektar++ community.

Duties and responsibilities

• Develop efficient software algorithms and implementations for high-order spectral/hp element methods for compressible flows on high-performance parallel computing platforms within Nektar++.


• Collaborate closely with other members of the Nektar++ team

Essential requirements

• Practical experience within a research environment and / or publication in relevant and refereed journals


• Experience of dealing with other researchers, engineers or physicists


• Practical experience of collaborative software development using C++


• Knowledge of modern C++ language and template meta-programming


• Knowledge of software-development best practices


• Knowledge of parallel programming using MPI


• Knowledge of high-order spectral/hp element methods


• Knowledge of compressible flow research methods

Those appointed at Research Associate level

Hold a PhD (or equivalent) in Computer Science, Engineering or a closely related discipline.

Those appointed at Research Assistant level

A first / masters degree (or equivalent) in Computer Science, Engineering or a closely related discipline.
