Marine and Coastal Engineering
The QUB Marine Research Group (MRG), School of Natural and Built Environment (SNBE), are using the power of supercomputing to model offshore and coastal structures. Many tools developed in the group can be applied to a wide range of engineering problems, but a special emphasis lies on the design and development of marine renewable energy.
Wave energy converters are machines built to convert the energy in water waves into electrical energy. Those devices must be tested and optimised to provide maximum efficiency and power while surviving the most challenging offshore conditions. Any device must thus be tested for a large range of wave characteristics, shape variations and power take off settings.
A single simulation considering all the physical processes around the free surface is already challenging, so HPC applications are essential to cover the entire design space.

Numerical methods developed by the group have also been used for the simulation of tidal turbines and in the design of a novel concrete offshore wind towers.
