A coupled electromechanical and hydrodynamic time domain simulation of a direct-drive generator connected to a heaving buoy for wave energy conversion is presented. The system is based around a novel power take-off unit referred to as Snapper. The simulation is based primarily in MATLAB using its built-in Ordinary Differential Equation (ODE) solvers. These solvers act on the data derived from electromagnetic finite element analysis and from the WAMIT wave interaction simulation software. Test results of a generator prototype for comparison with the electromechanical simulation are also presented.
