The National Renewable Energy Laboratory (NREL) and Sandia National Laboratories (SNL) have developed WEC-‐Sim to provide the wave energy converter (WEC) design community with an open-‐source simulation tool. WEC-‐Sim models the BLOCKIN BLOCKIN system BLOCKIN BLOCKIN dynamics BLOCKIN BLOCKIN of BLOCKIN BLOCKIN WEC BLOCKIN BLOCKIN devices BLOCKIN BLOCKIN using BLOCKIN BLOCKIN multi-‐ body dynamics methods and simulates hydrodynamic forces using coefficients predicted from potential flow models. In this paper we describe the methodology used in WEC-‐Sim and demonstrate the use of the code by simulating three WEC devices. Specifically, we model a two-‐ body point absorber and two oscillating surge devices. For each device we describe how the WEC-‐Sim model was setup and present simulation results, BLOCKIN BLOCKIN such BLOCKIN BLOCKIN as BLOCKIN BLOCKIN predictions BLOCKIN BLOCKIN of BLOCKIN BLOCKIN device BLOCKIN BLOCKIN motions BLOCKIN BLOCKIN and power production. For verification and validation purposes, results are compared to corresponding results from other modeling tools and experimental data. BACKGROUND AND MOTIVATION Open-‐source numerical modeling tools have helped the wind energy industry achieve commercial viability by enabling the rapid development, analysis, and certification of wind turbine systems. The recent emergence of the WEC BLOCKIN BLOCKIN industry BLOCKIN BLOCKIN in BLOCKIN BLOCKIN the BLOCKIN BLOCKIN U.S. BLOCKIN BLOCKIN and BLOCKIN BLOCKIN across BLOCKIN BLOCKIN the BLOCKIN BLOCKIN globe BLOCKIN BLOCKIN has created a need for an equivalent set of WEC design and analysis tools to help advance WEC technologies. Device developers are currently relying heavily on commercial modeling tools, such as OrcaFlex, WaveDyn, and AQWA to meet their modeling needs. However, with the wide range of device archetypes currently being developed, and the fast pace of innovation in the WEC BLOCKIN
