Siemens PLM Software - Siemens PLM Software’s Nx Nastran Solves World’s Largest Structural Analysis Problem

Shattering its Own Previous Record, NX NASTRAN Solves FEA Problem with Half-Billion Equations “Virtually Overnight”
New Delhi, December 18, 2008 - Siemens PLM Software, a business assemblage of the Siemens Industry Automation Division and a arch all-around provider of artefact lifecycle administration (PLM) software and services, today appear a computational break-through in absolute bound aspect appraisal (FEA) technology. Using commercially accessible hardware, the accepted assembly adaptation of the company’s NX™ NASTRAN® software was able to break a structural appraisal botheration with a half-billion equations “virtually overnight.”
The appraisal was conducted to simulate the behavior of an absolute aeroplane addition anatomy ability a angle test. The consistent botheration admeasurement of 500 actor equations was auspiciously completed in beneath than 18 hours of delayed time and burst Siemens PLM Software’s antecedent almanac – appear in February 2006 – which was aswell set by NX NASTRAN for a agnate problem. To accommodate perspective, a structural appraisal of an absolute auto anatomy modeled with carapace elements, could be apparent with about 100 actor equations.
“Our barter accomplish some of the world’s a lot of adult products, acute acutely abundant bound aspect models to accomplish the band-aid allegiance all-important to ensure their above and safety,” said Chuck Grindstaff, arch technology administrator of Siemens PLM Software. “Simulating the annihilative wing-bending analysis is an abnormally important basic of basic artefact development in aeroplane accomplishment and the 18-hour turnaround time provides a band-aid around overnight. As a result, our customers’ workflow action can advance uninterrupted.”
“Such ample botheration sizes were advised absurd just a few years ago, both from a after accurateness and computational aggravation point of view,” added Dr. Louis Komzsik, arch after analyst of Siemens PLM Software. “Today, we can confidently adumbrate that analytic a one billion blueprint botheration will be achievable in the abreast future. And with the approved adeptness of NX NASTRAN to break these huge problems, brainstorm how fast it can break the added archetypal appraisal problems encountered accustomed by our customers, above a advanced array of industries.”
Technology detail
The FEA archetypal apparent by NX NASTRAN consisted of one hundred actor grids alternating with about 98 actor carapace and 49 actor solid elements. The consistent bound aspect botheration consisted of 500 actor equations and had added than 600 actor all-around degrees of abandon if a beeline changeless appraisal with a individual amount action was executed.
The appraisal appropriate 1069 minutes, or 17.8 hours of delayed time on an IBM Power 570 server. The computer absolute eight POWER 6 cores at 4.7 GHz, 64 GB of anamnesis and 24 striped disks of 148 GB accommodation each. The appraisal acclimated 42.4 GB of memory, accomplished 30.3 Tera Bytes of I/O operations with a 2.26 Tera Byte deejay footprint.
