NESSUS is a modular computer program employing state-of-the-art methods for performing probabilistic analysis of structural/mechanical systems. NESSUS can be used to assess component/system reliability, to identify important random variables, to provide information for risk-based decision analysis and reliability-based optimization, and develop designs that are more cost-effective and reliable than those developed using traditional deterministic design methods.
A 30-day demonstration version of NESSUS is available at no cost to evaluate the general capabilities of the software. This is a reduced capability version with limits on the number of random variables and only allows analytical functions. Follow the Demo link to download this demonstration version.
