CFD for Designers
Posted Thu January 10, 2002 @01:04PM
Print version Email story Tweet story
News A recent Desktop Engineering article describes how CFD software has migrated from an "experts only" tool to one which design engineers can apply during the design process.

The primary obstacle for the use of CFD in design has been that design engineers are required to perform a variety of tasks - only a small part of which might be analysis.

“So the problem was that these engineers were using these tools every once in a while,” says Ed Williams, president of Blue Ridge Numerics. “You’re trying to teach them all these complicated things that they are going to forget the next time they go to use it a month later.”

Credit for the change is given to the great advancements in grid generation in the past 20 years, along with ease-of-use enhancements by the flow solver vendors. Tighter integration with CAD has also been a big factor in making the tools easier to use. The newest version of Blue Ridge Numerics CFdesign software, for instance, was designed to be tightly integrated with Pro/Engineer from PTC. The software launches directly from within Pro/E and works directly on the Pro/E geometry.

Hardware HP has introduced new entry-level and mid-range technical computing workstations.

The entry-level HP workstation x1100 offers workstation performance at a PC price. The mid-range HP workstation x2100 features integrated chip technology enabling frequencies up to 2.2GHz and up to twice as much L2 cache.

Graphics are the NVidia Quadro2 EX which can be upgraded to the new ATI Fire GL 8800 mentioned here previously.

CAD Data Exchange State of the Art

Print version Email story Tweet story
News Cadalyst has examined the CAD data exchange issue with their recent articles covering STEP vs IGES and CAD data translation services.

The STEP vs. IGES article polled six MCAD vendors on various issues surrounding the use of the neutral data exchange formats. The questions covered developer support, end-user support, problems in the formats, and future direction of neutral CAD data exchange. The article includes tables of MCAD translator support for the two protocols.

Four CAD data translation services were reviewed in the second article. The services are available over the internet as ASPs (application service providers). The services range from methods to translate the data through the STEP neutral format, to design intent feature-based native translation. Each of the services is available on a pay-per-use basis. The article concludes with a number of tips for using ASP data translation services.

CFD for Automobile Aerodynamics
Posted Sun January 06, 2002 @11:20PM
Print version Email story Tweet story
News Automotive Design & Production has an article about the use of Exa's CFD code in the automotive industry.

Exa has won the support of a number of automotive manufacturers by modeling not only their test vehicles, but the entire wind tunnel as well. This provided the automotive engineers with a true comparison between the test and analysis results. The CFD results correlated very well.

Now that CFD analysis is viewed as a valuable analysis tool, Exa is promoting analysis early in the design process.

“It’s a real ‘What if?’ tool,” says Stephen Remondi, president, CEO, and co-founder of Exa Corp. “Since you can change your model quickly, cost effectively and have confidence in the simulation, you’re able to try out more aggressive, more creative ideas in the time available.” While it’s presently in the domain of engineers and aerodynamicists, they’re working on a digital interface for designers so that 3D models will be, in effect, “sculpted” as if they were in clay.
Applications include vehicle aerodynamics, underhood thermal management, HVAC, powertrains, air filters, exhaust systems, disc brakes, intake and exhaust manifolds, valves and aeroacoustics.
