Pointwise Awarded Research Contract
Posted Tue October 07, 2003 @09:08AM
Print version Email story Tweet story
Geometry Pointwise, Inc. has been awarded a research contract from the U.S. Naval Air Warfare Center for a feasibility study of software techniques for converting computer-aided design (CAD) data into solid models suitable for computational fluid dynamics (CFD) meshing. The 6-month effort (with a potential 3-month extension), was awarded under the Navy's Small Business Innovative Research (SBIR) program.

The lack of integrity in CAD data is one impediment to the effective use of CFD for solving engineering problems of interest to the Navy. One example of a simulation impeded by poor CAD data involves aircraft operating in and around a ship's airwake. These CFD simulations are hindered by the fact that CAD data for the ship and/or aircraft when delivered to the engineer is not suitable for CFD meshing due to two main problems. The first problem involves geometric surfaces that don't properly fit together and instead contain gaps and overlaps (more specifically, they "leak"). The second problem involves excessive detail, both in the number of entities used to define the geometry (for example, using thousands of surfaces to define the hull) and in the level of geometric detail included in the CAD file.

News Fluent and Dassault Systems have announced a strategic partnership which will have Fluent join Dassault's Software Community Program as a CAA V5 Software Partner. Fluent will develop, market, and sell CFD solutions based on the Dassault Systèmes Component Application Architecture (CAA V5).

Through this partnership, Fluent will complement the existing V5 suite of Analysis solutions and provide V5 users with fluid flow simulation within the standard CATIA®V5 environment. Initial product plans include Fluent/FloWizard for CATIA V5, a CAA V5 Based fluid flow simulation solution.

Users will then be able to fully prepare their CFD analysis model within the CATIA V5 environment. By maintaining associativity between the design and analysis models, Fluent’s CAA V5 Based products will reduce the time required for analysis of design iterations and allow CFD to be applied more readily to product optimization.

News AFC Air Flow Consulting AG - Swiss leader in CFD computation services - has released a Newsletter. The News are in German (at the moment) and will be published twice a year. Newsletter #1 can be found at

The first News deals with:

  • Actual projects (contaminant control in pharmaceutical industry and airflow around the new stadion of Zurich)
  • About AFC, the staff, the competences
  • AFC is moving! Due to more people working at AFC, the offices are getting narrow. AFC is therefore moving to new and large office rooms at a new location in Zurich

Hope you have fun with the Newsletter and sorry for no english version. Please contact me if you would like a translation.

John Deere Buys Linux Supercomputer for CFD Analysis
Posted Mon October 06, 2003 @11:34AM
Print version Email story Tweet story
News Linux Networx announced today John Deere is using a Linux Networx™ Evolocity® cluster supercomputer for next generation product development.

John Deere is using the Linux Networx cluster for advanced engineering analysis including computational fluid dynamics and structural finite element analysis. The cluster has demonstrated improved computing performance for the company, performing several classes of analysis jobs at more than double their previous speed. The flexibility of Linux cluster technology also allows John Deere to make the cluster available as a central corporate resource to be tuned for multiple applications in the future.

Linux clustering is a method of linking multiple computers together to form a unified and more powerful system. The Linux Networx cluster designed for John Deere uses 24 AMD Athlon MP processors, Clusterworx and ICE Box™ cluster management tools from Linux Networx and STAR-CD software from CD adapco Group.

“The cost advantage of clusters is outstanding, and with companies like Linux Networx delivering turnkey clusters optimized for engineering designs, our clients are regularly achieving fast solutions previously accessible only to supercomputers," said Steve Feldman, Director of Software Development for CD adapco Group.
