A CFD Haiku
Posted Mon December 10, 2001 @05:45PM
Print version Email story Tweet story
CFD Haiku As a tribute to the "art" of CFD, we are kicking off the Official CFD Review Haiku Poetry Contest. A haiku is a small contemplative poem which valorizes nature, color, season, contrasts and surprises. For our contest, the topic must be related to the field of CFD. The basic haiku format is three lines of 17 syllables arranged in a 5-7-5 pattern.

You are encouraged to send in your CFD haiku for publication here each week. There is no reward other than perhaps personal enlightenment. So, silence the mind, yield to spontaneity and send in your CFD haiku today.

This week's CFD haiku:

Difficult question...
what flow field hidden within?
computer reveals

Application: CFD Used to Study Surface to Air Missles

Application Scientists at the NAS Division's Applications Branch have used NASA's Cart3D CFD software to analyze the unsteady flight of infrared-guided, man-portable surface-to-air missles (SAMs).

The Cart3D solver's capabilities were extended to simulate the unique flight characteristics of the SAMs which make them difficult to simulate computationally. Scientists used the NASA Advanced Supercomputing facility at Ames Research Center to conduct the steady and unsteady simulations on both a 1024-processor and 512-processor SGI Origin 3000 system. More than 720 simulations were completed on meshes totaling almost 2.4 billion cells.

"Results from preliminary NAS studies presented to the DIA have been met with enthusiastic support," said Mike Aftosmis. The steady and unsteady results have shed new light on the flight characteristics of these missiles.
The Cart3D package is an inviscid Cartesian grid flow solver which provides end-to-end simulation of three-dimensional flows around complex vehicles.

News COSMOS/Flow, the CFD package from Structural Research & Analysis Corp, has been certified for UGS' Solid Edge Version 10. Embedded in Solid Edge and featuring an easy to use Windows-native interface, COSMOS/Flow is fully associative with Solid Edge Version 10.
"The COSMOS/ suite of analysis products is perfect for Solid Edge users who need to perform stress, flow or electromagnetic simulation, but don't have the time to learn three different analysis programs. With COSMOS/ software, all analysis is done within the same easy to use interface, dramatically reducing the learning curve and speeding up productivity." says Suchit Jain, VP of Marketing for SRAC.

ANSYS CFX AEA Technology has announced that they will be porting their CFX-5 CFD software to HP's Intel Itanium platform. The work will be done for the HP-UXi 64-bit operating system.
“CFX sees great performance potential for this technology. HP is a leader in developing IA-64 with Intel and we expect that their support of HP-UX11i on their new Itanium platforms will give CFX customers a stable and very fast simulation platform for running CFX-5. In keeping with the advanced CFD technology employed in CFX-5, CFX wants to ensure that our customers can make use of this promising new computer architecture as soon as possible” commented Dr. Michael Raw, Vice President CFX Product Development.
The Intel Itanium processor is designed to scale to 512 processors and features 64-bit memory addressing which will enable engineers to tackle much large problems than possible on 32-bit machines.
