CFD Software Improvements Yield Benefits for Designers

Print version Email story Tweet story
News Automotive Design and Production has posted an article about recent improvements to CFD software and their effects on design engineering.

For years, CFD vendors have taken the geometry from computer-aided design (CAD) to build the CFD model for analysis. But, says Thomas Marinaccio, director of CFD Consulting Services for software vendor CD adapco Group in Melville, NY, it’s been a one-way transfer. “It’s dead,” he says, meaning the designer can’t modify the geometry once it’s inside CFD.

Funny, all the CFD vendors say their products are integrated to CAD. “That can mean several things,” explains Judd Kaiser, technical solutions specialist for fluids and meshing at Ansys Canada Ltd (Waterloo, Ont., Canada). Does it provide good data transfer? Does it provide a clean translation of the CAD geometry to the CFD meshing environment? Does the parametric model automatically update when the CFD mesh updates? Does the integration truly provide two-way connectivity? That is, once an optimum solution is understood in CFD, can the designer push changes back into the CAD system?

Print version Email story Tweet story
Hardware The Silicon Graphics Prism family stands apart in the visualization world, designed for breaking through barriers imposed by other computer system architectures and fundamentally reshaping the boundaries of what is possible.

"The pace of scientific discovery and engineering innovation has never been more aggressive," said Paul McNamara, senior vice president and general manager, Visual Systems Group, SGI.

The system allows researchers to:

  • Gain increased insight by easily working with all data, all the time, at terabyte data sizes and beyond
  • Discover hidden details by working at 100M Pixel resolutions
  • Eliminate time consuming data preparation by interactively visualizing billion polygon models

Leveraging the power of true scalability, Silicon Graphics Prism provides the ability to easily scale system resources within a system to meet each customer's interactive visualization needs. Whether you are a power user working individually with demanding data sets, part of a team interacting in a collaborative environment, or solving the world's most demanding problems by roaming through terascale data sets, the scalable architecture of the Silicon Graphics Prism family of products meets your needs today while providing the capability to easily expand in the future.

Application: CFD Used to Improve Water Treatment Systems

Application By David J. Burt,
Senior Engineer,
MMI Engineering

A secondary clarifier is the final treatment stage of a traditional activated sludge sewage works. It separates solid precipitate material from effluent water prior to discharge. Because of recent changes in environmental legislation, many treatment works in the UK are required to carry increased throughput or meet more stringent effluent quality limits. This means that more clarification capacity is needed. But with land in urban areas scarce and construction costs high, there is an increasing need to maximize the performance of existing units rather than build new ones.

The standard technique for designing a final clarifier is mass flux theory. However, this method uses a one-dimensional settling model and cannot account for the ‘density current’ flow typical in a clarifier.

ANSYS FLUENT Please join Fluent Inc. and its partners Concepts NREC and Engineous Software for the second in Fluent's Turbomachinery Webinar Series; Fan and Blower Design, on Thursday, October 21, 2004 at 2:00 pm ET.

This is an excellent opportunity for designers, analysts and managers to see how state-of-the-art software can be used to reduce costs and time-to-market by streamlining design, analysis and optimization of rotating fluid machinery.

The seminar will be of interest to all Turbomachinery designers who want to see how off-the-shelf software from Fluent, Concepts NREC, and Engineous can be used to build a complete design and analysis system, with a focus on fans and blowers.

The seminar will include one hour of presentation material along with a 15-minute question and answer period.

New Software: FLOVENT V5 Provides Usability, CAD Import and Gridding Improvements
Posted Fri October 15, 2004 @04:03PM
Print version Email story Tweet story
News Flomerics has introduced Version 5 of Flovent airflow design simulation software offering substantial improvements in the areas of usability, CAD import and numerical stability. The menus have been redesigned in the new release to more intuitively guide the user through the modeling process. Analysis accuracy has been improved with a grid-based dissection CAD import method that provides better handling of complex building geometries. Numerical stability has been increased by refining Flovent's unique object-based localized gridding.

Usability has been improved by redesigning the top-level menu system so that it is more consistent with design-based project creation. The node tree has been simplified and focuses on a hierarchical view of the project geometry. The file menu now lists the most recently opened files so they can be quickly re-opened. Menu picks that provide importing and exporting of projects and assemblies have been repositioned on the file menu for easier access. There have also been significant performance improvements in accessing the data associated with very large projects, very often encountered in building applications.

CFdesign For the second consecutive year, Blue Ridge Numerics has been selected to the Deloitte Technology Fast 50. Moving up eight spots from 2003, Deloitte now places Blue Ridge Numerics as the twenty-fifth fastest growing technology company in Virginia. The recognition is based on percentage of revenue growth over five years. The announcement was made October 7th during an awards ceremony at the ESPN Zone in Washington, D.C.

“To make the Deloitte Technology Fast 50, companies within the Virginia region must have had tremendous revenue growth from 1999-2003. Deloitte applauds Blue Ridge Numerics for having the long-term vision to develop technologies that change the way manufacturing companies deliver new products to market,” stated Gary H. Tabach, office managing partner of Deloitte’s McLean Virginia office.
