Welcome to the LUSAS website

LUSAS develops, markets and supports a range of engineering analysis software products all based upon the LUSAS finite element analysis system.

  • LUSAS software products can solve all types of linear and nonlinear stress, dynamics, composite and thermal engineering analysis problem, across a range of engineering industries.

  • LUSAS software options for particular LUSAS software products extend the analysis capabilities available for use on applications such as vehicle load optimisation, steel and composite deck design, and rail track-structure interaction analysis.

  • LUSAS case studies show illustrative and interesting uses of LUSAS software on projects and applications around the world.

  • LUSAS video presentation sessions show particular software products and features in action.

Typical Structural Applications


Latest Software Release

LUSAS Version 15.1-0 - this exciting new release of the software contains numerous new facilities and improvements, as well as error fixes for reported issues. It provides:

  • Improved Reporting - including max/min and extreme results for envelopes and combinations, one-click member reports, and auto-updating of report data.
  • Improvements for staged construction - camber, displacement and incremental displacement table facility now provided.
  • Better ease of use - including improvements to saved views, graphing, easier introduction of joints, and a family of new piecewise inelastic joints for seismic and soil joint modelling.
  • Vehicle Load Optimisation improvements - AASHTO 6th and 7th editions and CAN/CSA S6-06 now supported via LUSAS Traffic Load Optimisation facility; onerous results tables and non-planar decks now supported.
  • Enhancements for design - including feature-based results, rigid joints and floor loading.

Software was uploaded on 29 July 2015.
