Abstract
To design a wave energy conversion system, time domain numerical modelling is required. This is due to the nonlinearities present in the system from different sources, including hydrodynamic forces, device dynamics, control mechanisms, and mooring lines. Combining model accuracy with the efficient calculation of hydrodynamic forces in the time domain can be challenging and time consuming to implement. This paper describes unified computational framework that handles those challenges efficiently for different types of wave energy converters. The framework is implemented as a toolbox that contains the key components of a wave-to-wire model. Finally, a short validation of the model and comparison with wave tank experiments is shown.
