SGI Announces Itanium-Based Linux System
Posted Tue May 29, 2001 @01:22PM
Print version Email story Tweet story
Hardware SGI has announced that their Silicon Graphics 750 system for Linux will be available in July. Based on the 64-bit Intel Itanium processor, the system is designed for high-performance computing.
The Silicon Graphics 750 features advanced computational processing in a compact form factor capable of scaling up to two processors and 16GB of memory. The availability of the Silicon Graphics 750 will accommodate and enable the most demanding power users in the technical and high-performance computing markets such as computational fluid dynamics, mechanical computer-aided engineering (MCAE), computational chemistry, scientific computing and visualization.
This is SGI's first entry into the Itanium-based workstation arena. Given that the Itanium was designed to be scalable up to 512 processors, we can expect some serious hardware soon.

Post Processing Prabhu Ramachandran writes "This is to announce the availability of the MayaVi Data Visualizer version 1.0. This is the first public release. MayaVi is a free, easy to use scientific data visualizer. It is written in Python and uses the Visualization Toolkit (VTK) for the graphics. It provides a GUI written using Tkinter. MayaVi is free and distributed under the GNU GPL. It is also cross platform and should run on any platform where both Python and VTK are available. MayaVi is based on ideas from an earlier CFD data visualizer called VTK-CFD. The original VTK-CFD code base has been completely rewritten and redesigned. The resulting project has been renamed MayaVi and has been SourceForged. MayaVi supports the VTK data format that can handle rectilinear, structured and unstructured grids. It also supports binary structured PLOT3D files. MayaVi can visualize scalar and vector fields and is under active development. For more information, downloadable sources, screenshots, installation instructions, documentation etc. visit the MayaVi home page at:"

News AEA Technology will hold a free seminar on their mixing analysis package ProMixus. The seminar is scheduled for Wednesday May 30th at Loughborough, UK.
CFX-ProMixus includes libraries of industry-specific impeller and tank configurations with the ability to model Newtonian or highly viscous non-Newtonian fluids. CFX-ProMixus automatically calculates and produces detailed quantitative reports on important mixing parameters, e.g. mixing time, power requirements, shear levels and velocity fields amongst others.

News While not strictly CFD news, many of us do use solid modeling software from SDRC to begin the CFD analysis process so I decided to put this up on the site. EDS has agreed to purchase SDRC for $950 million in cash, as well as, buy up all publicly held shares of its Unigraphics Solutions subsidiary.

The companies will combine under the UGS name to become EDS's fifth line of business. Unigraphics President and CEO Tony Affuso will become president of the new business.

EDS will pay a premium of 42% over SDRC's closing price yesterday or $25 a share.

“In the last 24 months, we have seen the beginning of a network-based revolution in the way products are designed, developed and manufactured,” said Dick Brown, EDS chairman and CEO. “UGS has given us a window on this change and on the emergence of product lifecycle management, where digitized information is shared instantly and globally. Now is the time to move quickly and decisively to capture opportunities in this space.”
Brown noted the SDRC acquisition would bring EDS 7,000 clients, 85 percent of whom are new to EDS, and greatly expand relationships with companies including Ford, Mazda, Honeywell, Nissan and Nokia.
“Most importantly, we gain substantial software capability in a rapidly emerging market with significant ‘pull-through’ revenue for services from our other four lines of business,” Brown said.
Now why didn't I buy a large block of SDRC shares last week?

Application: CFD Used to Optimize Paper Mill Burner
Posted Thu May 24, 2001 @10:28AM
Print version Email story Tweet story
Application Pulp & Paper Online is running an article detailing how the Coen Company was called in to an Alabama pulp and paper mill to increase burner coke firing and correct flame impingement problems on the kiln refractory. In addition, to reduce operating costs, the mill wanted to use a combination of fuels including natural gas and waste oil with particulates.

Using CFD, Coen modeled the existing burner's temperature contours, coke firing rate, flame shape and radiative heat flux to the kiln refractory.

The CFD modeling persuaded the customer that a properly designed burner system could eliminate flame impingement, increase coke firing, and meet their production requirements.

Within 16 weeks, Coen delivered a multi-fuel dual air zone kiln burner, which successfully started up in a week. The new burner conveyed the coke in an outer air zone while an inner air zone spinner created a strong recirculation zone to stabilize the difficult to burn coke fuel. For precise flame shape control, CFD modeling created unique drillings for the gas and oil firing nozzles.
