Abstract / Description of output

Transient simulation of full wave energy systems
is computationally intensive due to the requirements for hy-
drodynamics, multibody dynamics and power take-off system
aspects, particularly electrical, to be calculated simultaneously.
By exploiting the relatively loose coupling between aspects of
the PTO simulation and motion calculation in a wave energy
converter, a multi-rate solver may be used which takes multiple
smaller time steps for some parts of the model in between larger
steps for the motion simulation. This paper describes such a
system and applies it to a reference wave energy converter model.
Initial tests indicate that there are clear advantages to the system
in terms of computational efficiency while retaining a high level
of fidelity in all model components.
