HIGHWAVE involves a lot of numerical simulations, dealing in particular with extreme sea states and using nonlinear wave propagation models. ICHEC, the Irish Centre for High-End Computing, provides core-hours to three kinds of projects. Class A projects are intended for consortia concerned with high impact problems. Prof. Dias was successful with his Class A application. The project has been given 5M core-hours. It will start on 1 June 2020 and will last for a couple of years.
