| Finite Element Analysis, Structural design, Yacht Design, Composites | Team New Zealand's Black Magic, the yacht that recently won the coveted America's Cup in the seas off San Diego, had an important element in its pedigree: analysis with MSC.NASTRAN. The initial geometry was read from Maxsurf into EDS/Unigraphics using an IGES file. The first mesh was developed using Unigraphics/GFEM. Because the yacht is a floating structure, a great deal of effort was spent by Team New Zealand in arriving at loads and boundary conditions that would correctly model both hydrostatic pressure loads and loads from the masts and stays... | |

| Finite Element Analysis, Ship Design | Shipbuilding companies in the Far East, especially in Japan, are pioneers in the use of finite element analysis. Since the mid-1960s, Japanese shipbuilders have been in a lead position in the technical evolution of finite element modeling (FEM), which has helped them maintain their business prosperity. It was in the early 60s that FEA technology was first introduced to Japanese shipbuilding companies.... | |

| Foils, Aerodynamics | Laws of Aerodynamics and Lift. In academia, wings are analyzed by considering the physics of the fluid. There are three known laws that come into play for the standard flight conditions. These are: 1. Conservation of Mass 2. Conservation of Momentum 3. Conservation of Energy These laws can tell you what causes lift for your particular airfoil... | |

| Foils, Aerodynamics | A Tale of Two Airfoils. Why is there a difference in the profile drag coefficient between two symmetrical airfoils of the same maximum thickness and at the same Reynolds number? The drag coefficients (as computed by VisualFoil) are 0.005927 and 0.004181 for the NACA 0012 and NACA 66-012 respectively. The Reynolds number is chosen to be 3 million so comparisons can be made with experimental data. The following article provides a brief explanation... | |

| Foils, Hydrodynamics, Keel Design | Keel Parameters and Performance By David Vacanti. Reprint From Sail Magazine August 1985. In the design of a sailboat keel, it is not possible simply to write down all the optimum proportions and draw the keel accordingly. A designer must cope with several limitations, and he or she is not always free to use those optimum values. | |

| Graphic File Formats | Neutral file formats, information about IGES, DXF, and STEP. Neutral files and neutral file interfaces are needed in order to exchange product data between CAD systems. Also direct translators exist but the the number of needed translators is becoming large if there are many CAD systems involved in the data transfer. For each pair of CAD systems to be communicated two translators are required, one for each direction. | |

| Surface Modeling | Fitting Smooth Surfaces to Dense Polygon Meshes by Venkat Krishnamurthy and Marc Levoy. Recent progress in acquiring shape from range data permits the acquisition of seamless million-polygon meshes from physical models. In this paper, we present an algorithm and system for converting dense irregular polygon meshes of arbitrary topology into tensor product B-spline surface patches with accompanying displacement maps. This choice of representation yields acoarse but efficient model suitable for animation and a fine but more expensive model suitable for rendering... | |

| Sail, Multihulls, Aerodynamics | Square top sails by Mr. S. Hape. What are these strange looking mainsails appearing on many of today’s racing multis? At first glance it appears that these boats are missing the top of their masts! The answer is quite simple - These are "Square Tops."... | |

| Foils, Aero-Hydrodynamics, Yacht Design | Wing Sections for fast Sailing Boats by Dr. Martin Fischer. For fast boats, like multihulls, it is not an easy task to find appropriate wing sections to be used as rudder blades. To understand that we should first make clear how the requirements for a rudder look like. First of all the rudder must ensure to hold the course in all conditions... | |

| Aerodynamics, Sail | The case for transport sail craft. The next oil crisis will create a new round of interest in alternative energy, renewable sources. The economics of military and commercial sailing will again be hotly debated by naval architects and marine engineers.

| Aero-Hydrodynamics, Sharks | Unusual skin that allows deep-ocean sharks to cut through water as if it were air may someday help engineers reduce air drag on airplanes. Hammerheads and some other kinds of sharks can swim up to 45 mph in part because they have dermal denticles, scalelike projections on shark skin whose microstructures help to reduce fluid drag. The denticles are attached to tiny-subskin muscles... | |

| Hydrodynamics, Dolphins | All dolphins have a similar streamlined, torpedo-shaped bodies. A dolphin has extremely smooth, firm and velvety skin, which helps them to slip through water with apparent ease. Water resistance is greatly reduced and this effect, together with the body's streamlining and the power of the flukes, allow the dolphin to swim at high speeds... | |

| Surface Modeling, Computational Fluid Dynamics, Meshing | Volume gridding for CFD starts from a geometric model for the body surfaces. It is argued that NURBS based geometry definitions are fundamentally unable to deliver the degree of consistency and accuracy required for this purpose. The reasons for this are explored. Relational geometry is proposed as an advantageous alternative... | |
| |

| Surface Modeling, Solid Modeling | We describe four Relational Geometry (RG) based implementations: two commercial surface modelers and two solid modeler prototypes which implement RG on top of commercially available solid modeling kernels. RG is applicable to the vast majority of design projects which do not proceed linearly from beginning to end. It is especially suited to conceptual design and to creation of parametric series of models as part of a design optimization process... | |

| Computational Fluid Dynamics, Aerodynamics | This lecture is devoted to the study of irrotational plane flows of an inviscid fluid. The ultimate goal is to determine the force exerted by a uniform flow on a Joukowski wing.
