Ship longitudinal strength in Simulation

Has any tried to use Simulation to analyze global longitudinal strength of a ship's hull while afloat? I have attempted to do this, but I am not pleased with the results. To start with I am simply considering a "prismatic" barge. My methodology was:




1) Import ship midship section from an already created AutoCAD file

2) extrude midship section over desired length

3) apply steel material



4) Start static analysis

5) Treat model as beam

6) Apply buoyancy pressure to under water part of hull as non-uniform distribution

7) Add cargo weight as equally applied load to deck

8) Mesh and run
