"It" was a design engineering project shrouded in a veil of mystery. A cryptic posting made to the Web site Inside.com sparked a wild amount of anticipation and speculation about "It."
Strive
for Greener Environment: HVAC Manufacturer Uses CFX To Improve Energy
Efficiency, Reduce Environmental Impact
As living standards rise
precision manufacturing proliferates around the world, air-conditioning
equipment accounts for more and more energy consumption. Stricter environmental
regulations and increasing environmental consciousness of air conditioning
equipment users demand more efficient compressors with less impact on the
environment.
Houston-Based Valve Designer, Engineering Firm Depend On ANSYS to
Verify Design
One of the most important operations in hydrocarbon
refining is a process known as fluidized catalytic cracking (FCC). A special
type of slide valve controls the catalyst flows. Typically, these valves are
installed in refractory lined piping approximately five feet in diameter and
weigh 20,000 pounds. Operating temperatures inside the valve range from 900 to
1,400 F. Occasionally, temperatures go as high as 1,800 F for brief periods,
called excursions, or short term upset conditions.
India-Based Auto OEM Reduces Front Axle Weight by 40% with
ANSYS
The rapid developments in numerical simulation techniques, faster
computing ability, and greater memory capacity, are allowing engineers to create
and test industrial equipment in virtual environments. Through finite element
analysis (FEA), these sophisticated simulations provide valuable information for
signing and developing new products, as well as perfecting existing ones.
Manufacturers have found this method eminently useful, as it helps them to
achieve better productivity at a lower cost per unit, and develop engineering
components that are easy to manufacture, and which make the most economic use of
their materials.
Water-Cooled a??Microchannela?? Redesign for a 'Hot' ASIC Verified
With ANSYS FLOTRAN
The electronics business and the news about it are
dominated by microprocessors and the RAM chips at the heart of so many devices.
Much of the electronicdesign business, however, is low-volume and even
one-of-a-kind devices for testing and related applications. The analyses focused
on the chuck interface between the die and the way its cooling fluid works with
the heat spreader and base plate. The specific device is a large ASIC
[application-specific integrated circuit] array in test equipment.

standards is comprised of building and electrical codes that are essentially
regulatory. The other is safety standards that are essentially physical
properties.

common welded one. He is regarded as a visionary in the area of trailer makers.
Avoiding Big Problems on "The Big Dig" with ANSYS
Mechanical
For many years, the citizens of Boston, Mass. (U.S.A.) have
been victims of gridlock traffic on the Interstate 90 roadway, also known as the
Central Artery. Opened in 1959, today the elevated expressway can no longer
accommodate the volume of daily traffic traversing the heart of downtown Boston.
ANSYS
ICEM CFD on Supercomputer Helps Designers 'Cut Corners' in Race Car
Design
Ita??s not just how fast a racecar goes that makes a design a
winner, ita??s also how fast it goes around the curves. In large part, speed in
the curves is a function of how much a??downforcea?? is created by air flowing
over the cara??s surfaces. Thus, much of the computational fluid dynamics (CFD)
analysis of race cars has to do with making sure the airflow pushes down on the
car as it does with how smoothly the car slips through the air. The major
benefit of CFD in auto racing: Cutting down the high costs of building prototype
cars and physically testing in them in wind tunnels and on race tracks.
Leading
Motorsport Team Races to Get Car Design Right the First Time
Next to
Mario Andretti, there is, perhaps, no more recognizable name in American
motorsports than Roger Penske - racing and winning in the U.S. since 1958. After

ANSYS
and Battle Readiness: Prognostic Model Keeps Helicopters Flying
For 20
years, the U.S. has asked its military to do more with less. Even as resources
are trimmed, the armed forces are asked to take on new missions in faraway
places. All too often, this is done with equipment that is far beyond the
service life for which it was designed. Despite their increasing age, aircraft
remain in service because replacements are not being acquired.
ANSYS
"Forensic" Engineering Studies
Although designers and engineers work
diligently to ensure the viability and safety of their designs before they are
built, sometimes, unforeseen circumstances can occur. Whether they are the
result of mechanical failure, natural phenomena or acts of sabotage, each year
these incidents cause billions of dollars worth of damage and significant loss
of human life to even the best engineered designs, if not their utter
destruction.
Pilot
Structural FEA Program Unveils Substantial Savings
Even if you are not really a "gear-head," you probably know that the engine under your car's hood utilizes a balanced air/fuel mixture to generate power. What you might not be aware of is that when you turn the key, only 25% of the energy created by your engine is actually transferred to the vehicle's operation. The remaining 75% must be evenly distributed from the engine to the environment inside and outside the vehicle. This process is known as "heat transfer" and it is important for maintaining a vehicle's performance, as well as minimizing the amount of harmful emissions produced by the vehicle.
