The objective of the study was to perform resistance calculations on a ship in calm water, for several ship speeds and water depths. 2 geometrical configurations were actually studied : infinite width or restricted width (30 meters). For the restricted width, 2 kind of modeling were used for the banks : either they reflect the waves or either they smooth them.

FINE™/Marine software suite was used to perform the resistance calculations, using the dedicated C-wizard to speed the set-up. Only half of the ship was meshed using HEXPRESS™, thanks to the symmetry of the configuration. Shallow water modeling was activated.

Post-processing includes efforts and displacements for each calculation.

The pictures below show the water free surface elevation (perspective and top views) for a calculation with confined width and reflecting banks.
