Commercial RANS based CFD programs have become an accepted method of making predictions of flow patterns, pressures and the forces resulting from water flow around a ship's hull. The main advantages of using a commercial code are that the user interfaces are flexible and well designed and the codes are validated by a larger number of users in many fields of fluid dynamics and thermodynamics. The disadvantages are that they are very general in their application, and may be more complicated or less reliable to use than a custom made code for a very specific application. The commercial RANS based CFD program used at Memorial University of Newfoundland is Fluent (Fluent Inc., 2005). Meshes for this program can be created in a number of different ways, but Gambit (Fluent Inc., 2005) is the product supplied by the same company for this purpose, and was the program used for this study.
