WEC-Sim (Wave Energy Converter SIMulator)

WEC-Sim (Wave Energy Converter SIMulator) is an open-source wave energy converter simulation tool. The code is developed in MATLAB/SIMULINK using the multi-body dynamics solver Simscape Multibody. WEC-Sim has the ability to model devices that are comprised of rigid bodies, power-take-off systems, and mooring systems. Simulations are performed in the time-domain by solving the governing WEC equations of motion in 6 degrees-of-freedom.

Developers and Contributors

WEC-Sim is a collaboration between the National Renewable Energy Laboratory (NREL) and Sandia National Laboratories (Sandia), funded by the U.S. Department of Energy’s Water Power Technologies Office. Due to the open source nature of the code, WEC-Sim has also had many contributions from external collaborators.
