Abstract
WEC-Sim (Wave Energy Converter SIMulator) is an open-source code for simulating wave energy converters, jointly developed by National Renewable Energy Laboratory and Sandia laboratories in the United States. WEC-Sim is developed in MATLAB/SIMULINK with Simscape Multibody, which solves the multi-body dynamics of the system. A brief overview on the methodology and the capability of the WEC-Sim model will be presented, followed by an investigation on how WEC-Sim was used for different WEC applications.
