Graphics For Your Desktop and Laptop
Posted Tue August 14, 2001 @06:25PM
Print version Email story Tweet story
Hardware There are some hot new graphics cards out for your desktop workstation and Cadence has a fresh review for you to study.

Cadence tested the 3Dlabs Wildcat II 5110, the ATI Fire GL4, and the ELSA Gloria III - all top of the line cards. The cards were run through the SolidWorks 99 and 3D Studio Max 3.1 Benchmarks. The best? The Wildcat, but it will cost you around $2200US.

For you mobile engineers, nVIDIA announced today at SIGGRAPH 2001 the Quadro2 Go. Offering the same graphics engine as the gForce2 Go, but adding additional support for engineering applications (such as antialiased lines and overlay support), the Quadro2 Go allows engineers to design in 3D on a mobile platform.

“There is a clear need for mobile 3D workstations,” stated Jen-Hsun Huang, president and CEO at NVIDIA. “Quadro2 Go-enabled laptops will transform the way design professionals work. Armed with a powerful mobile workstation, design engineers and artists are now able to create whenever and wherever they are inspired. And be able to demonstrate their work to customers and collaborators wherever they may be.”
The Quadro2 Go will be available in several OEM laptops this fall.

Solving the Mystery of the Extra Shock Wave

Application In the second of their Mysteries of Engineering Fluid Dynamics series, AEA Technology examines the reason behind an "extra" shock wave found on flow past a sharp wedge.

The case [pdf] examines supersonic flow past a 10 degree wedge and the creation of an oblique shock off the bottom surface which is parallel to the flow. It is an interesting application which explores the complex nature of a seemingly simple flowfield.

News In another step towards paving the way for mainstream CFD usage, FloWorks (a CFD plug-in for SolidWorks) has been certified as a Gold Product. The certification process involves three primary characteristics: single window integration, full associativity, and the ability to pass a rigorous testing and certification conducted by SolidWorks.

Is this a sign of the future for CFD?

Hardware Looking to purchase some new 3D PC graphics hardware and unsure about the best solution? Check out this review of the market from CADServer.

The article looks at the recent consolidation of the high-end PC graphics market with the aquisition of Intense3D by 3D Labs, the merger of Elsa/nVidia, and the sale of Fire GL Graphics by Diamond to S3 (now SonicBlue). The article also includes a brief run-down of the products soon to be launched by these companies.

ESI Group CFDRC has released version 4.2 of their compressible flow solver CFD-FASTRAN.

The solver, which supports arbitrary polyhedral elements and Chimera grids, is designed for compressible flow with moving multi-body dynamics. The latest version incorporates new distributed parallel technology which removes the need for PVM.

Volkswagen Engineers Use CFD for Thermal Management
Posted Tue August 07, 2001 @03:58PM
Print version Email story Tweet story
Application In order to optimize underhood thermal management systems (radiator, fan, etc) engineers at Volkswagen are using CFD to examine the airflow and temperature distribution in the engine compartment. CFD is used to simulate a number of "what if" scenarios such as, a vehicle under load or failure of a fan.

Volkswagen engineers have found that, in order to accurately simulate the engine compartment, the analysis should include:

  • representation of the heat exchanger packages
  • the effects of fans
  • reasonable inlet and wall boundary conditions (turbulence, etc.)
  • thermal radiation effects
  • conjugate heat transfer
