Application: CD-adapco's STAR-Works Reduces Development Costs
Posted Wed May 17, 2006 @11:49AM
Print version Email story Tweet story
Application CD-adapco, the leading provider of full-spectrum CFD solutions, today announced that partner VIASYS Healthcare had delivered huge savings in product development by utilizing CD-adapco's upfront CFD tool STAR-Works. By using STAR-Works early in their design cycle VIASYS was able to reduce the timescale for the initial design phase of a new ventilator from a year to just three days, saving several hundred thousand dollars in development cost.

VIASYS pneumatic specialist Steve Han and his colleagues were responsible for the redesign of an infant CPAP ventilator device. Continuous Positive Airway Pressure (or CPAP) is a method of respiratory ventilation used in the treatment of apnea, a condition in which a patient's natural external breathing suddenly stops due to a self imposed (but involuntary) obstruction to their airway.

Application: CFD Helps Diagnose High Risk Brain Aneurysms

Application University of Houston engineers are working with neurology specialists on new technology to help identify which brain aneurysms are at highest risk of rupture and could cause a stroke.

In A Stroke of Genius The Engineer Online looks at how CFD is used to study blood flow in realistic geometric models of aneurysms. Using the method, researchers were able to identify blood flow characteristics that may contribute to aneurysm formation.

"One of the key points is that aneurysms don't seem to form randomly," Metcalfe said. "They do seem to form at locations that are associated with the fluctuations in the flow of blood, leading to the question of what it is about the flow of blood that tends to correlate with the formation of aneurysms."

Application by Bob Cramblitt

Combustion Research and Flow Technology, better known as CRAFT Tech, says it likes to swim in data.

Not just any data, of course. CRAFT Tech immerses itself in terabyte-sized datasets used to simulate complex fluid dynamic and combustive problems. To swim in these waters requires large-scale, parallel architecture computers running specialized CFD codes and the most advanced visualization software.

A recently completed project called HiFAST (High Frequency Acoustic Suppression Technology) showcased CRAFT Tech’s ability to take full advantage of CFD visualizations at every phase of weapons system development. The project, conducted for the Air Force Research Laboratory’s Air Vehicles Directorate (AFRL/VAAI), culminated in a successful flight test of a device that controls internal weapons bay airflow and acoustics.

Perfect Flight At Last

News New flow simulation software developed at the Army High-Performance Computing Research Center (AHPCRC) incorporates automatic mesh generation technology directly in the flow solver allowing the mesh to adapt to changing conditions and geometries during the simulation.

In the Desktop Engineering article Perfect Flight At Last, Dr. Andrew Johnson of the AHPCRC describes how moving mesh CFD techniques offer new ways to model complex fluid-structure interactions such as a hummingbird’s hovering flight.

In early 2005, we began working with the new parallel programming language Unified Parallel C (UPC) with the goal of building new types of codes that would be difficult or impossible to implement using MPI. We quickly recognized that UPC would allow us to create a new type of CFD code that supported much more complex simulations, including dynamic mesh methods.
