Abstract

Highlights
•A fully nonlinear, coupled model of the Wavestar WEC has been created using open-source CFD software, OpenFOAM®.
•The response of the Wavestar WEC is simulated in regular waves with different steepness.
•Predictions of body motion, surface elevation, fluid velocity, pressure and load are compared with physical measurements.
•Model stability is shown under extreme motions, green water and break-up of the free surface.
