A NURBS-Based Computational Tool for Hydrodynamic Optimization of Ship Hull Forms

NURBS stands for a "Non-Uniform Rational B-Spline" type of surface. Ship hull forms are represented by NURBS in most of the modern Computer Aided Ship Design (CASD) environments. Computational fluid dynamics (CFD) based hull-form hydrodynamic optimization relies on CFD solvers to evaluate the objective functions in terms of the flow around the ship hull that is discretized by meshes. In order to conduct CFD-based hull-form hydrodynamic optimization efficiently and automatically, it is essential to develop an accurate and effective NURBS-based hull-surface modification technique and an automatic mesh generation tool.
