Love Hz

Print version Email story Tweet story
Hardware With the introduction of Intel's latest and greatest Pentium 4 processor, the megahertz race has hit 2 GHz. Intel rejoiced that the 2 GHz "barrier" was broken. (When did 2 GHz ever appear as a "barrier" - I've certainly not been waiting for it to be broken.)

To counter Intel's hype surrounding their barrier smashing, AMD has decide to embrace a Hz-less marketing campaign. Citing the "devaluation of MHz", AMD will now brand their processors by model number and will go so far as to forbid advertisers from reporting the processor clock frequency.

There has been some data to suggest that AMD is right. Processor clock frequency is only part of the equation when determining performance. Cycles per instruction (CPI), the number of clock cycles necessary to perform an instruction is the other important measure and it is here, because of it's shallower pipeline, that the AMD processor has the advantage. However, when have you seen CPI reported in a marketing ad? You just might soon.

Others wonder if all this MHz chasing is worth while. TenLinks.com has posted an editorial calling for the end of the megahertz race and a focus on cheaper computing.

Being CFD enthusiasts, we crave more processor power (whether it comes from Hz or CPI) and will always be interested in the fastest processor available. However, at this time, I'd say it's unclear whether the Pentium 4 is the better choice. Time will tell.

ANSYS FLUENT Fluent has released a beta version of their FlowLab CFD teaching software.

Designed to introduce fluid mechanics students to CFD in an easy to learn manner, FlowLab utilizes parametric templates to define the geometry and grid. It is possible for professors and advanced students to define their own parametric templates using tools which come with the software. Fluent envisions a growing library of templates being available over the web.

The beta version will be used this semester by students in several universities. During the beta period, Fluent will be working with the professors to refine the library of templates.

Help Desk Daniel Fuentes writes "My name is Daniel Fuentes, Engineering civil student of San Simon University from Cochabamba-Bolivia, I am doing my work for the degree of engineer. I am trying to modelling a reservoir of Laka Laka with the SSIMM model. in this task i have some problems on planing the grid.

i ask some criterius or guidelines for making the grid (planing grid). i have some criterius like:

  • The type of grid; structured and unstructtures
  • The powerful of the solver
  • the size of the grid
But i want to extend this criterius or have more organized the ideas."

Anyone have some tips on modeling a reservior they are willing to contribute? Post your tips in reply to this article.

Post Processing And CEI will give them to you FREE. With each new purchase of their EnSight visualization software, CEI is giving away a set of stereo viewing glasses and emitter.
"We're doing this to jump-start the use of stereo viewing, which can greatly enhance what you see and understand in high-end visualizations," says Kent Misegades, CEI president.
EnSight and EnSight Gold support stereo viewing on all UNIX, Linux and Windows platforms. So check out EnSight and go get yourself some cheap sunglasses.

Application: Cooling The London Coliseum

Application The London Coliseum was completed in 1904 and originally utilized plenum-style ventilation. Later, facilities were added to supply flow at the seating level and remove it at the ceiling. In 2000, cooling was added to the supply air.

Now, Arup is undertaking a complete redesign of the ventilation system. The new design will feature the more modern system of supplying cooling air at the ceiling and drawing it out at the seating levels. The three seating levels (dress circle, upper circle and balcony) complicated the design.

In order to optimize the airflow for maximum occupant comfort, Arup utilized CFD modeling of the coliseum.

The Future of Design Analysis (as ANSYS Sees It)
Posted Tue August 28, 2001 @06:30PM
Print version Email story Tweet story
News Paul Bemis, Vice President of Engineering at ANSYS, has written an article for Design News which looks into the future of engineering analysis and where it fits into the design cycle.

ANSYS got into the CFD game last year with the purchase of ICEM CFD so their views on the future have some implication for all CFD enthusiasts.

Bemis sees simulation occuring earlier in the design process, but at a reduced complexity spurred by the growth of application-specific GUIs. Another important prediction is continued expansion of web-based tools for sharing data. Bemis envisions a system in which no knowledge is lost from the early proof-of-concept stage through the final ready-for-production stage.

What's your view of the future of engineering analysis?
