Abstract
In this paper we provide an update on the status of the WEC-Sim project, both the code development and experimental testing efforts. Code development has been focused on adding features that improve the delity of the simulation including non-linear hydrostatic and excitation forces calculation, body-to-body interactions through coupled radiation forces, Morison drag, and more direct modeling of power take-off and mooring components through integration with PTO-Sim and Moor-Dyn. The experimental testing eort has the main objective of providing a comprehensive dataset with which to validate both WEC-Sim as a whole, as well as some of the newest features. The testing was divided into two phases, the rst of which was completed in December 2015, and are being conducted at the O.H. Hinsdale Wave Research Laboratory.
