UGS’ NX Nastran Sets the Standard for High Performance Computing; Enabling Real-Time Simulation Throughout the Lifecycle

NX Nastran Sets New Benchmark in its Category, Solving the Largest and Fastest Known Calculation

FOR RELEASE Monday, February 20, 2006

DARATECH SUMMIT 2006, CAMBRIDGE, Mass. – UGS Corp., a leading global provider of product lifecycle management (PLM) software and services, today announces new NX™ Nastran^® customers, and that NX Nastran set anew benchmark in its category by solving a 200 million degrees of freedom (MDOF) model - the largest and fastest known calculation of this type.

“This breakthrough extends our leadership in high performance computing,” said UGS Chairman, CEO and President Tony Affuso, who will announce the initiative during his keynote address today at the Daratech Summit 2006 event. “NX Nastran is a core element of our Lifecycle Simulation strategy to enable real-time simulation across the product lifecycle. We expect NX Nastran to solve problems up to a billion degrees of freedom in the near future. Its scalability and speed significantly improve productivity for our customers, enabling faster idea validation and accelerated innovation.”

Technology Specifics

The analysis was conducted to simulate the behavior of a wing structure under shear load conditions. NX Nastran executed the linear static analysis of a 200 MDOF model that was comprised of over 34 million quadrilateral shell elements and approximately 35 million node points.  The solution was obtained in seven hours of elapsed time during which 4.2 tera-bytes of input/output was processed using eight processors in shared memory parallel paradigm.  The highest amount of memory used was 20 giga-bytes and the disk space required was 971 giga-bytes.  These numbers represent an extraordinary breakthrough in the implicit finite element analysis industry.

The analysis was executed on a just announced IBM System p5 570 with 16 POWER5+™ processors running at 2.2 GHz and 128 GB of DDR2 memory.  The 1.4 tera-byte scratch file system was striped over 19 internal 15k rpm disks.

By combining several of the machines into a cluster and utilizing NX Nastran’s industry leading distributed numerical technology known as Hierarchic Distributed Memory Parallel (HDMP), NX Nastran will be able to solve similar problems up to a billion degrees of freedom in the near future.
