SolidWorks Helps Propel 32nd America's Cup Winners

DSP = displacement (cubic meters)

The boats are narrower now , along with commensurate developments in rig and sail technology are immense compared to previous designs. However one aspect of their performance hasn’t changed at all, and that is the fact that they go to windward incredibly well. The narrow tacking angles and general upwind performance makes them very well suited for match racing, such as the America’s Cup. In terms of dimensions, the boats have evolved with less beam and tend toward the maximum allowable displacement for stability.

Whether the America’s Cup Class Rule endures beyond this cycle of the Cup will be determined by the winner of the 32nd America’s Cup Match and the new Challenger of Record. With mutual consent they can decide to evolve the class rule further, or opt for an entirely new class of boat. Obviously, each direction has risks and rewards.

Racing yacht design is an extremely complex endeavor, and is often more akin to aerospace design that it is to more ordinary boat design. As you can imagine, designs and how they were arrived at are secrets of the utmost degree. Trying to obtain any information from either of the teams was next to impossible. However, I did get a few tidbits of what SolidWorks was used for on the respective teams from SolidWorks Corp. For the Alinghi team, the following components were designed using SolidWorks: hull, keel fin, winches, machined parts, and steering systems. For the ETNZ team, the following components were designed using SolidWorks: hull, steel keel fin, solid lead keel bulb, and deck hardware. It’s interesting that both teams say they used SolidWorks for hull design. It would be as interesting to know exactly to what degree SolidWorks was actually used for hull design, because hulls can consist of some very complex aerodynamic surfaces. All in all, though, a nice development for MCAD.

Editor’s Note: Alinghi defended its title on July 3, 2007, by a two-second winning margin in the seventh race, winning the match 5-2.

The Week’s Top 5

At MCADCafé we track many things, including the stories that have attracted the most interest from our subscribers. Below are the five news items that were the most viewed during last week.

View22 Offers Combined Solution that Extends Autodesk Inventor to the Web
View22 Technology Inc. ("View22")
a provider of 3D Web commerce and media products, announced an integrated solution between Autodesk Inventor, Autodesk Intent, and Immersiv, View22's 3D web software. The combination creates an automated end-to-end offering that spans entry of customer requirements through creation of custom order engineering designs and manufacturing documents. Autodesk and View22 have agreed to enter a co-marketing relationship in which Autodesk will recommend View22 as a preferred partner for providing web-based, thin-client 3D sales automation solutions for its current and prospective customers. View22 will recommend Autodesk as a preferred partner for 3D design and engineer-to-order products for its current and prospective customers. Autodesk and View22 have worked closely together to integrate the Autodesk Inventor and Intent product suites with Immersiv to create a 3D web-based engineer-to-order sales automation solution. This solution will be co-marketed by Autodesk and View22 to address mass customization requirements. In addition, View22's software platform now natively supports Autodesk DWF, DXF, and 3DS file formats

Dassault Systemes and PROSTEP AG Partner
Dassault Systemes (DS)
announced an expanded CAA agreement with PROSTEP, a provider of solutions for product data integration. PROSTEP will develop and sell a new PLM SOA (service oriented architecture) connector taking advantage of DS's ENOVIA SOA enterprise middleware architecture. The connector will allow ENOVIA users to view, access, manage, and collaborate across PLM content from heterogeneous data sources such as Teamcenter, Windchill, Agile, and SAP PLM. PROSTEP's OpenPDM allows integration of PDM components in the Intranet and facilitates data exchange with external partners via a uniform interface. It is a service-oriented, modular system that can be tailored to various system environments. OpenPDM provides interfaces to all leading PLM, PDM, TDM and ERP systems as well as to other systems or applications involved in the product development process, and supports the consistent and secure exchange of data between PDM systems

GibbsCAM Certified by Autodesk for Inventor 2008
Gibbs and Associates announced that GibbsCAM has been certified for Autodesk Inventor 2008 under the Autodesk Inventor Certified Applications Program. GibbsCAM is able to directly read in native Autodesk Inventor model files for process planning and toolpath generation. The Inventor-to-GibbsCAM add-in also allows Autodesk Inventor models to be directly transferred from within Autodesk Inventor to GibbsCAM. Updates to either part geometry or process parameters are easily accommodated by GibbsCAM's full associativity across geometry, process, and toolpath.

Chengdu Aircraft Selects VISTAGY's FiberSIM
VISTAGY announced a partnership with Chengdu Aircraft Industrial (Group) Co. Ltd., a Chinese supplier to the global aviation industry, to create a world-class 3D model-based composite aircraft design and manufacturing process based on VISTAGY's FiberSIM software. FiberSIM will be Chengdu Aircraft's software solution for all future composite part development programs. Chengdu Aircraft utilizes FiberSIM's comprehensive set of tools to develop composite aircraft products and parts, such as wing skins and rudders for commercial airliners, from early conceptual design through product delivery. A composites engineering process includes many unique methodologies, such as ply-based design, fiber placement, and tape laying, that are unlike any other product development process. FiberSIM supports composite methodologies and processes, and provides a platform for sharing design data across existing applications and downstream processes.

CD-adapco and Argonne National Laboratory (ANL) Win Benchmarking Exercise
CD-adapco announced that its Computational Fluid Dynamics (CFD) software, STAR-CD, produced very good void distribution results when compared to detailed void distribution experimental data in the BFBT benchmarking exercise at the 2007 BFBT-4 workshop. In the past decade, a significant amount of effort has been invested toward the simulation of boiling in Boiling Water Reactor (BWR) fuel bundles. The detailed void distribution inside the fuel bundle is regarded as one of the important factors affecting the performance of BWR fuel assemblies. In the steady-state microscopic grade benchmark of the void distribution, the evaluation team concluded that the results submitted from the U.S, Department of Energy's Argonne National Laboratory, obtained with the STAR-CD code, provide the best match with the measured detailed void distribution, when compared with two other major CFD codes. The results were obtained using STAR-CD and the Extended Boiling Framework developed by CD-adapco in collaboration with Argonne.

    It is always a pleasure to read what you write. It is easily understood with your choice of words. I wish I could do the same. I learned a lot of what goes on behind the watching of these boats in the water. I'm sure Las Vegas betting is already being done on this next Amerca's Cup Race. Good Write Jeff.
