The hydrodynamics of the water flow, such as currents, waves, tides and their interaction with the structure, play a significant role from an engineering perspective and are always an essential part of the entire modelling process. This chapter focuses on the numerical modelling of water flows and provides an overview of a large variety of numerical modelling techniques, including well‐established and recently developed methods and practices in industry and research. It discusses commonly used open‐source software for marine renewable energy (MRE)‐related simulations, in order to suggest freely available and validated numerical tools to potential modellers. It presents tables on the applicability of numerical models for simulating different physical processes, with a focus on MRE projects. The tables can be used as guidelines and decision‐making tools, according to the physical problem, available expertise and computational resources, and the required level of accuracy.
This is a chapter from Wave and Tidal Energy.
