Hello,

I'm a beginner with OpenFoam and currently I'm doing the simulation of underwater floating object with intact and damaged condition.

My project is quite similar with this paper "Investigation on a damaged ship model sinking into the water based on three dimensional SPH method" but I'm not using SPH to validate the exp results.

My floating object is a buoyancy tank (cylindrical shape) and it was moored with nylon line. The problems is, I have 3 cases for damaged condition and each of it represent different position and size of holes.

What I want see is that what will happens to the damaged floating object (cylinder) when I put the cylinder in the calm water, and the water enters in the cavity in the cylinder.

1) Will the cylinder float ?
2) Will it sink ? If it sink, either it will completely sink to seabed or it will float but the position at Z already reduce ?
3) What is the new position of cylinder when the water enters into the damage cylinder ?
4) Is there any function that indicate weight of floating object increase (mass of water displaced + mass of floating object) vary with time so the position of the floating object at Z direction will be changed also ?

Currently I'm trying to running the floating object below the water surface for intact condition to benchmark the position, but at somehow, it crash at the middle of simulation.

So, I really need help you guys to solve this issue.

Thank you.

Best regards,
Han

Hello guys,

Does anyone can help me to solve this problem ?

At least, kindly please give me some solution or hint to start my simulation.

Thank you.

Kind regards,
