Abstract Heave plates have been widely used in floating structures to improve their seakeeping dynamics by increasing their added mass and damping. Although scaled experiments have been conducted to study their hydrodynamics, an accurate numerical model is still lacking. Such a model is needed to overcome experimental limitations, including tank size constraints, extremely high or low KC motions, and impractical model scales, while capturing the complex nonlinear hydrodynamic behavior. The present study proposes a numerical framework for simulating forced oscillations of heave plates using advanced overset mesh techniques in OpenFOAM. The accuracy of overset interpolation strategies is examined, and superior results are shown by comparing with morphing mesh approaches. The numerical model is validated against multiple experimental studies, focusing on vortices and hydrodynamic performance to identify the most suitable turbulence model, SA-DDES. Finally, an improved numerical framework is proposed to overcome experimental constraints and further explore the hydrodynamics of heave plates.
