4. Results and discussions
The main purpose of this study is to demonstrate the capability of the general-purpose CFD solver of Star CCMþ in analyzing the seakeeping characteristics by using a personal computer. The presented results for all cases are discretized for single grid and time step, based on the experience of authors' prior calculations. Due to the high computational cost, verification and validation studies are not performed. All simula-
tions have been carried out on an eight-parallel cluster computer and it allows the approximating 6.5 million cells for simulation. Some results obtained after fifteen full days running on the computer are given in this section. To acquire the added resistance, two different computations were imple- mented: a calm water resistance computation and a sea- keeping computation in head waves. Both results will be presented discretely in the following sections.
