The Role of CFD in Virtual Engineering
Posted Tue December 18, 2001 @07:00PM
Print version Email story Tweet story
News P.S. MacDonald, Director and General Manager of CD adapco Group, has written an editorial on the value of virtual engineering and how he sees CFD being integrated into the design cycle.
Virtual engineering is not a route that allows half measures. To avoid building multiple prototypes, all aspects of product development must be captured and closely integrated. For example, vehicle design engineers may need to simulate a crash, and at the same time optimise underhood thermal management.

The article goes on to describe the steps being taken at CD adapco Group to help establish the virtual engineering process.

CFD Haiku This week's CFD haiku comes from willjefc:
Computer our friend?
Try a small mesh size problem
Testing not so bad.
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.

News Blue Ridge Numerics is offering a multimedia Guided Tour CD for users of Pro/Engineer. The CD showcases three examples of the high level of integration between CFdesign and the Pro/ENGINEER mechanical CAD system from PTC.
“We are offering an amazingly elegant solution for Pro/ENGINEER users,” says Jim Spann, vice president of Marketing for Blue Ridge Numerics. “This guided tour approach is a nice way to educate the thousands of engineers who face product performance challenges related to fluid flow and heat transfer.”
A free copy of the Guided Tour CD for Pro/ENGINEER users can be obtained by phone: 434-977-2764, Ext.108 or via the web site at www.cfdesign.com.

CAD Vendors on Data Exchange
Posted Mon December 17, 2001 @12:17PM
Print version Email story Tweet story
News Cadalyst recently asked six CAD vendors to address the problems with moving CAD data between applications. The article mainly speaks of moving data downstream to project management applications, but you can safely replace "project management" with "engineering analysis" in the description of data flow.

The CAD industry is (slowly) moving away from software co-existance to file translation to inter-process communication. The article describes the current capabilities and what is needed to make true CAD interoperability a reality.

News Metacomptech has released the latest version of their flagship CFD product. CFD++ Version 3.1 features additional physical models for conjugate heat transfer, porous media, swirling axisymmetric flow, an axisymmetric flow-straightener model, and a database of fluid properties.

The new version also has a number of enhancement for simulating rotating machinery and enhanced handling of multiple CPU runs.

Demonstrations of the new version will be available at the 40th AIAA Aerospace Sciences Meeting and Exhibit January 14-17, 2002.

Is Your Solution Converged?
Posted Thu December 13, 2001 @08:10PM

Solver In their latest newsletter, Fluent offers advice to engineers running CFD solutions on when to declare your solution converged.

The article covers the basics of solution convergence in a CFD simulation and discusses the level of convergence necessary for differing applications. For instance, a highly converged solution is required if you are examining minute details in the flow field as opposed to a case where you are simply looking for approximate flow features.

During the course of the iterative solution algorithm, the imbalance in each cell is a small, non-zero value that, under normal circumstances, decreases as the solution progresses. This imbalance is called the residual.
The article also describes some ways in which the solution convergence can be monitored. These include plots of the total residual, integrated quantities at surfaces (such as mass flow rate), and derived quantities, such as the drag coefficient.

In conclusion the article points out that solution convergence is only one part of overall simulation accuracy.
