Hello,


This is an advanced simulation and it comprises the following elements:


- Open Channel  - You need to use the VOF model ( volume of fluid)


-6DOF Dynamic mesh method - You need to use the 6DOF dynamic mesh method to simulate the object bobbing up and down


It is a transient simulation and it is perfectly achievable in ANSYS Fluent. You need to get all the properties for the 3D object ( Mass, Mass moment of inertia etc..) you need to represent the solid body as a cavity and you will have 2 fluid materials (Air and Water).
An example of this simulation in 2D:

Something similar in 3D:
