Models for ship hydrodynamic analysis
Hi,
Does anybody know the best model for analysis in the following cases? 1. Free surface (no waves) analysis for ship resistance (viscous and wavemaking) 2. Free surface (waves) analysis for ship resistance ( added, viscous and wavemaking) For the second case the tutorial recommends 6DOF with VOF but I do not want to analyze the ship movements in the first case so please recommends me a list of models to select. Thanks!

For the second one, you might need VOF+Morphor+6DOF:) 
apply an email so that i will send you a model....

Do I need to set the 6DOF? Please I would appreciate some help. Thanks 
depend on the results that you want to know you can use 0 degree of freedom or 6DOF. if you want to calculate drag in a specific speed you can handle the case considering it as a stationary body, but if you want to determine resistancevelocity curve or in cases you want to know how ship moves when it gradually speeds up you need to make a 6DOF simulation.
