Parametric Design of a Surface Combatant For Simulation-Driven Design and Hydrodynamic Optimization
Ship design is an iterative process and generally depends on geometric modeling of ship hull form. Designer has
to fulfill several different requirements developed out of regulations and customer’s needs. In the hydrodynamic part of the
design process, to be able to lead this system to an optimized design, the designer has to understand the behavior of the
system within the complete design space. 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.
While this can merely be seen as trial and error, simulation-driven design takes a different approach by using simulation
upfront to drive the development of the product’s shape. For this purpose, the hull form geometry has to be modeled on a
functional basis, i.e. the shape has to be defined and generated from a set of meaningful parameters. This paper focuses on
parametric modeling of a surface combatant to be able to create variants systematically for further optimization studies. This
issue will be addressed based on the CAESES as a unique CAD-CFD integration platform that serves as a workbench for
parametric modeling, optimization and data interfaces to external flow simulation codes.
