EDS Buys SDRC

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.

Application: CFD Helps Develop Faster Oil Containment Boom
Posted Tue May 22, 2001 @10:51AM
Print version Email story Tweet story
Application Researchers have used CFD to improve the speed at which an oil containment boom may be towed. Boom velocity is the determining factor in oil spill cleanup time because the boom can fail under hydrodynamic load. Using software from Fluent Inc., the CFD analysis focused on effects such as relative oil-water velocity, physical properties of oil and water, water depth, and boom draft.
Using software to simulate the interaction between oil, water, and boom offers a less expensive alternative to channel testing, thereby reducing the cost of designing improved oil booms. Once they have a validated CFD model, researchers can quickly change the boom geometry and evaluate design alternatives. Using CFD, researchers have now identified a type of boom that has the potential to increase critical velocity by more than a factor of four. When implemented, the new net-boom structure will decrease the time needed for oil spill cleanup, protecting the environment from the effects of the oil.

ANSYS CFX AEA Technology has boosted the performance of their CFX-4 breed of solver. Long known for its strengths in the chemical process and multiphase arena, CFX-4.4 has been updated with multiple frame of reference capability as well as improved parallel performance.
Other valuable enhancements include a new free-surface modelling tool that tracks accurately the gas/liquid interface through grid movement. For combustion applications, a multi-grey gas capability has been included, allowing more accurate calculation of radiative heat transfer in furnaces.
