WEC-Sim (Wave Energy Converter SIMulator)

WEC-Sim (Wave Energy Converter SIMulator) is an open-source code for simulating wave energy converters (WECs), jointly developed by the National Renewable Energy Laboratory and Sandia National Laboratories in the United States. WEC-Sim is developed in MATLAB/SIMULINK framework utilizing Simscape Multibody to solve the multi-body dynamics problem. WEC-Sim predicts the WEC dynamics through time domain simulations based on the radiation and diffraction method using hydrodynamic coefficients obtained from boundary element method based-frequency-domain potential flow solvers (e.g., WAMIT, NEMOH, or ANSYS AQWA). WEC-Sim is developed for the purpose of predicting, analyzing, and optimizing WEC dynamics and power performance.
