Application: Better Foam with CFX
Posted Wed January 28, 2004 @11:44AM

Application by Peter Bartsch,
CFX Berlin Software GmbH

Invented by Otto Bayer in 1937, Polyurethane (PUR) foam is an extremely common material, especially in our cars (bumpers, dashboards, seats, etc.) and in our homes (as insulating material for walls, pipes and refrigerators). PUR is produced by mixing alcohol and isocyanates. The resulting reaction generates gas bubbles which become trapped in the curing compound.

Pre-formed foam plastics are produced by casting processes, where the reactants are mixed just before they enter the mould. When foaming large structures, the curing process may start while the reactants are still being fed into the form, which can result in poor product quality with undesirable voids. To ensure successful filling, both the filling and foaming processes must therefore be optimized together.

Wolfram Research continues to provide advanced technical computing options for the latest and most-advanced microprocessor systems with the release of Mathematica 5 and gridMathematica for Linux on AMD64. As a reflection of Wolfram Research's rigorous software engineering standards, Mathematica 5 is among the first technical computing platforms specifically optimized for the AMD64 architecture--and it delivers impressive performance. The optimized Mathematica port outperforms a regular Linux version of Mathematica on AMD64 systems by up to 50 percent in typical scientific and technical calculations.

"Mathematica 5 for AMD Athlon 64 and AMD Opteron processors helps ensure that applications take full advantage of the AMD64 architecture performance benefits," said Ed Gasiorowski, director of Developer Relations, AMD's Computation Products Group. "Especially when dealing with large data sets, greater than the 4-GB limit addressed by 32-bit processors, Mathematica 5 will help deliver exceptional application performance."
