If you activate the two-way coupling in GMO model, then water will just roll the cylinder along.

Now, in order to assign velocity to the fluid, you can provide velocity at the boundary condition.

Thanks for all the work. I was thinking that perhaps it may be more meaningful to perform these analyses for longer runtime simulations.
