Outline of Final Research Achievements

The present project concerns with development and demonstration of Simulation-Based Design (SBD) framework for ship hull form design. Each basic component in a previously developed prototype is modified and extended, and reintegrated for a more capable SBD; where, real-ocean ship-cruising performance can be considered in the multi-objective reliability-based design optimization theory and fluid-structure interaction (FSI) analysis. In addition, the present framework is aimed to be a readily applicable, next-generation advanced design tool in the domestic shipyards by introducing tight interface with the most widely accepted CAD system in the design field. All tasks were successfully completed, and the realized SBD framework was shown very promising. Activities of the present work were reported in several international/domestic refereed journal and conference papers.
