I'm working on modelling a floating wind-wave hybrid system, consisting of a platform and six floaters, but the calculations do not converge.
I have explored the following strategies:

1. Adjusting the overall residual
2. Adjusting the residual of forces
3. Removing hinge constraints
4. Adding damping
5. Decreasing the off-diagonal elements in the IRF, such as surge-sway, surge-heave, etc.
   Despite these efforts, I have not been able to achieve convergence. Interestingly, reducing the number of floaters from 6 to 4 has yielded partial success in the calculations. I have uploaded the h5 file for reference.
