hello everyone

i am running ship simulation using flow 3d.
ship model was created using maxsurf.
ship weight, center of gravity & inertia tensor is determine using domhydro numeca.

here the problem i encounter:
1)my ship roll until capsize (upside down) using center of gravity data.
2)my ship rotates at z-direction using center of buoyancy data.

i wonder if data produce by domhydro numeca cannot be use at flow 3d.
and if the data is invalid, how to calculate the inertia tensor of floating object (ship)?

i'm very sorry including numeca software in flow 3d forum. hope anyone can help me. thank you.
