Hull Form Variation and Evaluation

Abstract

This paper give an overview of modern, computer-based methods for the systematic variation of ship hull form characteristics and for their evaluation mainly from a hydrodynamic point of view. Form variation is described for curves, surfaces and volume distributions on the basis of variational principles of shape definition. Examples illustrate the variability of the approach. Hydrodynamic evaluation focusses on numerical flow prediction and optimization strategies for flow modification. Perspectives are given for a direct coupling between from variation and hydrodynamic evaluation.
