This scholarship is funded by Swansea University, EPSRC and Airbus.
Start date: October 2020
Subject areas: Computational Techniques
Computational techniques that are based on the Finite Element or Finite Volume methods are regularly used by industries for the analysis and design of new products. The ability of these techniques to handle complex geometries rely on the availability of a robust, unstructured mesh generator.
Currently, for aerodynamic flow, at high Reynolds number, meshes containing 10’s of millions of points are used daily by Industry. However, a recent NASA report has predicted that by 2030, meshes containing billions of points will be required routinely by the Aerospace Industry in order to capture the complex, turbulent flow inherent in the design of the next generation of aircraft.
The use of Exascale computing platforms, which will be vital in order to perform these simulations in a reasonable timeframe, brings an exciting array of challenges at every stage of the simulation process, from CAD, through mesh generation and solution, to visualisation and analysis.
In this project we are proposing the development of a new parallel mesh generation scheme that can utilise 100’s of cores for the generation of such large meshes in a short timeframe.
In addition, the meshes generated must be able to resolve the thin, turbulent boundary layer that is present close to solid walls. Currently this is performed using advancing layer techniques that grow layers along a single normal from each surface point. However, these meshes are often of a poor quality in the vicinity of ridges and corners of the CAD model and are unable to capture the complex flow patterns in their vicinity.
This will be addressed by enhancing the boundary layer generation through the implementation of a “multi-normal” approach that will provide meshes that better cater for the complex flow features near ridges and corners that are becoming increasingly important in modern designs.
This project is at the forefront of the move into Exascale computing by the Aerospace Industry and the successful applicant will be working closely with Airbus in order to deliver a significant leap in their capability.
Candidates should hold a minimum of an upper second class (2:1) honours degree (or its equivalent) in Engineering or similar relevant science discipline (computer modelling). Programming ability is required.
