Among the challenges currently being faced by the wave energy industry, there are the ones related to the mathematical and numerical modelling of Wave Energy Converters (WECs) and WEC arrays. Various levels of physical are reflected on the dynamics of such systems. Oftentimes, the term ‘nonlinear’ is employed, because the mathematical modelling brings dynamic equations to be solved that are indeed nonlinear in nature, however, these nonlinearities may arise in different ways: from the wave excitation pressure field on the WEC to the mooring system dynamics, or the Power -Take (PTO) dynamics. In the case of point absorbers interconnected, or connected to a central floating platform, the connection is normally performed by airms and hinges. In the case, the appearance of nonlinear geometric onstraints is unavoidable. It is a challenge to model, both mathematical and numerically, the exact multi-degrees-of-freedom (dof) coupled dynamics of such mechanical systems.
