Print version Email story Tweet story
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

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

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.

ANSYS FLUENT Fluent has announced the release of the latest version of their general purpose pre-processor for CFD. GAMBIT 2.0 features an updated geometry kernel which allows for direct access to Pro/ENGINEER's geometry engine and support for ACIS 6.3.

Also new to this release is GAMBIT's ability to automatically refine the mesh in areas of strong curvature and near small gaps. An example of this technology was displayed in the IMR Meshing Maestro award-winning mesh.

A new version of G/Turbo has also been released with GAMBIT 2.0. G/Turbo is an application specific pre-processor integrated into the GAMBIT interface. G/Turbo is a tool which enables the rapid generation of meshes for turbomachinery applications. A unique feature of the pre-processor is the ability to create both structured and unstructured meshes. This allows simple geometries to be created very quickly while also providing a path for analysis of more complex models. G/Turbo is supplied as an add-on to GAMBIT 2.0.
