SwRI Wins R&D 100 Award For NESSUS Probabilistic Analysis Software

SAN ANTONIO—(BUSINESS WIRE)—July 20, 2005— A general purpose software program for computing the probabilistic response or reliability of engineered systems has received a 2005 R&D 100 award. R&D Magazine has selected Southwest Research Institute's(R) NESSUS Version 8.2 as one of the 100 most significant technological achievements of the past year.

NESSUS 8.2 is a commercial version of software originally developed by a team led by SwRI as part of a 10-year project for NASA to develop a probabilistic design tool for the space shuttle main engine. Co-developers are Los Alamos National Laboratory, NASA Glenn Research Center and Mustard Seed Software.

NESSUS 8.2 simulates variations and uncertainties in loads, geometry, material behavior and other user-defined inputs to compute probability of failure and probabilistic sensitivity measures of engineered and natural systems. The software has been successfully applied to a diverse range of problems in aerospace, gas turbine engines, biomechanics, pipelines, geomechanics, automotive systems, defense, weaponry and infrastructure.

"NESSUS is a practical tool for assessing uncertainties and predicting reliability to support decisions involving cost or safety critical problems," said Dr. Ben Thacker, manager of SwRI's Reliability and Materials Integrity Section and a developer of the software. "It is particularly useful for extremely large and complex problems and for one-of-a-kind systems, where testing is impractical or impossible."

NESSUS Version 8.2 includes a sophisticated JAVA-based graphical user interface, three-dimensional probability contouring and results visualization, capabilities for performing advanced design of experiments and sensitivity analysis, a probabilistic input database, and state-of the art interfaces to many third-party codes including ABAQUS(R), ANSYS(R), LS-DYNA(R), MSC.NASTRAN(R) and ParaDyn(R).

SwRI has won 29 R&D 100 awards since 1971. This year's awards will be presented Oct. 20, 2005, in Chicago. For further technical information about NESSUS, contact Thacker at 210-522-3896 or visit www.nessus.swri.org.

SwRI is an independent, nonprofit, applied research and development organization based in San Antonio, with more than 3,000 employees and an annual research volume of more than $399 million.
