Hydrodynamic Optimization of a Ship Hull via Simulation-Driven Design Method

In today’s common design processes it is mostly the modeling inside of a computer aided design (CAD) system that drives the process, while design performance is usually checked in the end by simulation. In recent years, researchers have worked for application of CAD and CFD methods integrated and simultaneously in order to speed up the preliminary design and analysis stage and make it more efficient. As a result of this and similar developments in modeling the geometry, a new concept has emerged: Simulation-driven Design, SDD. This methodology can be used to scan the complete design space and yields actual trend indications for all considered and varied design variables. Finally, by utilizing formal optimization algorithms, and this is the most consequent implementation of simulation-driven design, the simulation is really used to produce shapes, rather than just evaluating them. In this paper, it will be focused hydrodynamic optimization of a frigate type surface combatant based on Simulation-Driven Design approach. Optimization of a frigate type hull form for different objective functions was carried out completely automatically by the proposed methodology. CAESES (formerly called Friendship-Framework), a unique CAD-CFD integration platform, will be used to create a fully parametric model from a set of parameters and manage the entire optimization process. Firstly, the hull form will be modeled as fully parametric according to the determined parameters. This initial hull form will be modified by the change of the determined variables in the optimization process managed by a genetic algorithm and alternative forms will be produced. Software for performing resistance, seakeeping and stability analysis will be collected under a single roof by means of CAESES and optimization work will be performed.
