Ship Hull deterioration CFD
 

AOA sir, I am trying to do CFD of ship's hull (ship body under or surface of water) deterioration. Simply problem is that the ship is standing at jetty ( place where ship stays) where there is a dirty water. The dirty water contain different kinds of elements. Some of them cause the hull to degrade ( similarly as you can see in creep procress or corrosion takes place). How to do CFD for ship hull degradation and which software is to be preferred? How to tackle this problem please help me out.
Thanks
