- NESSUS is a modular computer software program for performing probabilistic analysis of structural/mechanical components and systems.
- NESSUS combines state-of-the-art probabilistic algorithms with general-purpose numerical analysis methods to compute the probabilistic response and reliability of engineered systems.
- Variations in loading, material properties, geometry, boundary conditions, and initial conditions can be simulated.
- Many deterministic modeling tools can be used such as finite element, boundary element, hydrocodes, and others.
- NESSUS offers a wide range of capabilities, a graphical user interface, and is verified using hundreds of test problems.
NESSUS was initially developed by SwRI for NASA to perform probabilistic analysis of space shuttle main engine components. SwRI continues to develop and apply NESSUS to a diverse range of problems including aerospace structures, automotive structures, biomechanics, gas turbine engines, geomechanics, nuclear waste packaging, offshore structures, pipelines, and rotordynamics. To accomplish this, the codes have been interfaced with many well-known third-party and commercial deterministic analysis programs.
