Fast random wave generation in numerical tanks [PDF]
Proceedings of the Institution of Civil Engineers - Engineering and Computational Mechanics, 2019 Generating and absorbing random waves in numerical models is a challenging problem, in particular when meaningful wave statistics should be generated to meet design sea-state requirements. The methodology presented herein allows for the generation of random wave fields (free surface elevation and velocities) to be reconstructed in time and in space by
