NESSUS allows you to treat parameters of your existing model as random variables
to quantify the reliability of your design.

1 Powerful Interfaces
NESSUS provides direct interfaces to most popular analysis codes, including
Abaqus, ANSYS, MSC Nastran, and MATLAB.

2 Advanced Methods
NESSUS uses some of the most advanced reliability analysis and uncertainty
quantification methods available anywhere.

3 Cross Platform GUI
The NESSUS graphical interface is easy to use and available for Windows and
Linux.
 

 


NESSUS OVERVIEW

 * 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.
