- 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, pi
