I am a final year undergraduate Faculty of engineering university of peradeniya. I'm doing a research call "Impact of tsunami generated objects on coastal structures using Computational Fluid Dynamics".Therefore I developed a Tsunami like wave using Ansys Fluent (below i attached Geometry of the flume and Tsunami like wave) now i struggled in how to floating a object (like box shape or disc shape) on the wave and how to hit with any structure (basically a wooden pannal)

Please Can anyone help me?
