Shore CFD are pleased to announce the release of MeshPilot 1.0, a PC-based structured mesh generation tool. Download your copy free of charge from our website www.shore-cfd.com.
About MeshPilot:
With MeshPilot, you can:
- Visualise any two-dimensional block-structured (multiblock) mesh.
- Generate two-dimensional structured meshes for airfoils. You can do
this fully automatically, or with as much direct control over mesh parameters
(dimensions, spacing, geometry) as you need.
- Rapidly modify your existing airfoil meshes.
About Shore CFD:
Shore CFD produce mesh generation software, specializing in tailored, automated
solutions for specific topologies.

| SGI Improves NASA Designs |

The goal at the NASA Advanced Supercomputing (NAS) Facility
is to provide sufficient computing
power to enable scientists and engineers to test their
designs in a “virtual wind tunnel.” Traditional wind
tunnel testing is time consuming and expensive —
requiring the construction or alteration of physical
models for each test — and even the most powerful
wind tunnel cannot simulate the conditions of the
launch and reentry of space vehicles.
Until the arrival of the 1,024-processor SGI Origin
3800 system, the computing power needed to make
the virtual wind tunnel a reality was unavailable.
Complete modeling of one aircraft configuration during landing required up to a year on a Cray C-90, imposing
serious limits on the use of simulation. The Origin
3800 system can run the same configuration in a
matter of hours, so, for the first time, scientists
can routinely use simulation to validate their designs under
varying conditions. “The Origin architecture has
created a revolution in computational fluid dynamic at
NASA and will fundamentally change the way aircraft
are designed in the future,” said Jim Taft, co-director,
Terascale applications group.
The ability to do advanced simulation has already
proved its value in NASA’s mision to design a new
reusable launch vehicle to replace the space shuttle.
During simulation of the X-37 drone, designed to be
dropped from the space shuttle to test reentry, a
serious flaw was discovered that would have led to
catastrophic failure. Millions of dollars and months of
time were saved because of the advanced capabilities
enabled by the Origin 3800 architecture.

| Research: Engineers Discover Secrets of Soccer Free Kicks

Three collaborating groups of researchers have used wind tunnel testing, computational fluid dynamics (CFD), and other computer simulation techniques to unravel some of the underlying mysteries behind "bending" a soccer ball during kicking, which will be a feature of the upcoming Soccer World Cup in Japan and Korea this year. This technically very difficult "art" of scoring goals from the dead ball "free kick" situation has been perfected by such world class soccer players as Brazil's Roberto Carlos, Germany's Michael Ballack, and England's David Beckham. Inspired to uncover the science behind the "free kick" and the soccer ball's dynamic flight, engineers from the University of Sheffield's Sports Engineering Research Group, Yamagata University's Sports Science Laboratory, and Fluent Benelux have carried out a fundamental scientific and engineering analysis of this exciting part of the "beautiful game."
Sports Engineering is a new discipline that applies standard engineering principles and techniques to the research, design and development of external devices used by athletes and sports people to enhance their performance.

Idaho National Engineering and Environmental Laboratory
Engineers at the Idaho National Engineering and Environmental Laboratory (INEEL) used computational fluid dynamics (CFD) analysis to determine the cause of a catastrophic failure in a recuperative flameless thermal oxidizer (RFTO), used for the destruction of hazardous compounds. When the unit's feed tubes melted, resulting in system failure, it was unclear whether the cause was a design flaw or operator error. Physical examination of the unit could not conclusively resolve the issue, so INEEL engineers were asked to recreate the failure scenario as a computer simulation. Working from data in the operation logs, they analyzed the last run of the oxidizer using CFD. The results clearly showed why the tubes melted. "The design of this particular model was such that there were recirculation eddies in the inlet plenum," explains Mike Rynearson, a Principal Engineer at INEEL. "These eddies caused below normal air flow into one of the feed tubes. That, combined with higher than normal propane levels at startup and the hot soak bed condition, caused the oxidation front to move into the low flow tube, causing it to overheat and fail. Once it melted, the others quickly followed.
