6DOF Dynamic mesh for a floating rigid body in fluent v20
 
Hi everyone,
This is being my first post on this amazing platform.
Actually, for my project work, I am trying to simulate a rectangular plate of dimensions (7.5*7.5) with 0.1m thickness over a wavy surface of ocean water. The condition was that the plate should be considered as a rigid plate that can easily float on the water surface and also can move with waves. I have tried different ways to analyze it with some normal kind of mesh and boundaries if I get some movements of the rigid plate then I will apply a very fine mesh for that with smaller timestep and more iterations.

I am suffering from the 6DOF dynamic mesh problem, while I don't have much knowledge of that but I knew that fluent v20, v21 can run dynamic mesh without UDF. I have tried with mass and inertia tensor values but couldn't find the impact of waves on a plate.

The geometry is quite simple, I have used a fluent multiphase VOF model with both open channel flow and open channel wave BC and gravity in the -Y direction. The system was ideally considered as ideal wave (Sinusoidal wave) and ocean current is not included yet(initial avg flow velocity is Zero).

If there are any suggestions regarding this, please let me know.
or any kind of help would be appreciable.
