Hi everyone. I'm trying to carry out a simulation of a Roll decay test of a ship in OpenFoam 2.1.1. I've modified the floatingObject tutorial, using snappyHexMesh to implement the ship's hull.

When I start the simulation the p-rgh field seems like this


but quickly, at time 0.001, it seems like the next image


There's a strange lack of pressure at the bottom of the ship, which comes with a very strong pitch movement. The COG linear velocity in Z axis rises about 1 m/s in 0.005 seconds. I've tried many different meshes, bigger and smaller, with more or less cells, but the problem is still here. Please help me, I need to carry out this simulation, it's part of a very important project.

Thank you very much in advance.
