New Software: FORTRAN Flow Chart Tool Available
Posted Sun August 22, 2004 @08:14AM
Print version Email story Tweet story
News OmegaChart ver. 1.1 is a FORTRAN FlowChart generator. It converts a FORTRAN source code to its FlowChart equivalence. The generated flowchart is ported into an Excel file.

With OmegaChart 1.1, you can untangle the programming logic in a spaghetti code and therefore generate visual documentation of the execution path.

While other analysis tools only provides you "assembly level" info such as calling trees, Omega Chart provide detailed "module level" logic such as if-elseif-endif constructs, loops and nested loops.

With omega chart, you can easily minimize the use of GOTO's and therefore "modernize" your code.

News Hilson Moran, one of the leading building services engineering consultancies has agreed a new four year licence arrangement with Fluent, the world’s leading Computational Fluid Dynamics provider, to use its Fluent CFD simulation software tool.

The use of Fluent CFD is now an important tool in designing complex buildings such as those undertaken by Hilson Moran, providing the ability to accurately simulate physical phenomena including external air flows for pedestrian comfort studies, internal air flows for the design of naturally ventilated buildings, thermal comfort studies in large enclosed spaces and the spread of smoke generated through fire. Using Fluent CFD such analysis can be accurately conducted, either during the design stages or retrospectively to confirm the expected performance, providing greatly reduced risk within the design and commissioning process.

CAD-based CFD Attracts Design Engineers

News A feature article at Desktop Engineering highlights the changes that CAD-based CFD has had on the adoption of CFD by design engineers.
"CAE has been an elite subject, with complex tools that were easy to forget dedicated to their use," says Dr. Ashok Das, manager of the Center for Modeling and Simulation at Applied Materials, Santa Clara, CA, manufacturers of semiconductor wafer processing equipment. "Nowadays, not many companies can afford many dedicated analysts. My vision is to bring CFD and FEA tools to the desk of design and process engineers."
Owen Warr, project engineer with Zero Zone, Inc., North Prairie, WI, makers of display coolers, freezers, and refrigerated merchandising cases, has had more than 15 years of experience using a variety of CAE tools. "When it comes to CFD, I remember when I had to write my own programs in Fortran, get geometry from 2D AutoCAD, then merge the program and geometry into Abaqus to run CFD. The dramatic changes in CFD since then are almost surreal," he says.

Application: CFD Used to Improve Missile Control
Posted Fri August 13, 2004 @04:43PM
Print version Email story Tweet story
Application A new desktop engineering article covers the development of a novel flow control system for missiles using actuators and advanced control algorithms. Instead of traditional hinged control surfaces, the aerodynamic surface contains an embedded system of miniature sensors on the outer surface, control actuators, and a real-time feedback controller just below the surface, all of which are unseen from the exterior. Displacement of the actuators creates a large effect on the flowfield around that region.
To validate its research findings and test active flow control system prototypes, ORI’s Aerodynamics Group relies on low- and high-speed wind tunnel tests and CFD simulations. "By combining CFD analysis with wind tunnel experiments," Patel explained, "we are able to reduce the total turnaround time for feasibility studies as well as systems development."

News Join ANSYS for one of a new series of one-day educational seminars in the US Southeast entitled Advanced CFD Technologies Featuring ANSYS ICEM CFD and CFX. At this free seminar, you’ll learn how you can tackle CFD challenges—from pre-processing to solution to post-processing—quickly, accurately and cost-effectively.

Using a combination of real-world customer examples and live demonstrations, our experts will discuss how ICEM CFD and CFX can shorten product design times and improve product development processes. In the morning session, you’ll learn how ICEM CFD improves grid generation and the afternoon session will inform you how the advanced solver technology in CFX provides quick and accurate results for complex, real-world problems.

Application: CFD Leads to Better Filter Design
Posted Wed August 11, 2004 @11:47AM
Print version Email story Tweet story
Application Extraction, a leader in semiconductor contamination measurement, has introduced a new filter system which puts proven technology in a significantly smaller footprint, enabling users to lower cost of ownership in deep UV (DUV) lithography.
"By using sophisticated computational fluid dynamics flow modeling techniques, we've succeeded in putting all the power and long-life filter protection of the E3000 in a much smaller footprint," David Ruede, Filtration Group Manager. "A smaller footprint quickly translates to significant savings in cost of ownership and gives users more installation flexibility. These are important advantages as new fabs ramp production and older fabs install new generations of lithography tools."
