The present paper report on the use of an interface tool between software for CAD (Computer Assisted Design) and CFD (Computational Fluid Dynamics). Experimental obtained data for the drag force acting on a mode! prototype of the HUGIN 3000 and data obtained from a Computer Aided Analysis of the drag force carried out by CFD, is also presented. The HUGIN 3000 was developed in the nineties, by Kongsberg Maritime and FF1 (Norwegian Defence Research Establishment). The experimental results in this paper, origins from a model lest carried out by Marintek. The range of Reynolds numbers for both the experimental data and the computational results is 2.707xl06 to 1.146xl07. The agreement between the experimental data and the computed results is good. Particularly for the highest Reynolds numbers, the prediction of drag force by CFD seems to be remarkable good.
