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.

  • Selected software products are available in LT, Standard or Plus versions.

  • Analysis capabilities for particular LUSAS software products can be extended by using Nonlinear, Dynamic, Thermal/Field, Fast Solvers and other software options. 

  • Case Studies pages show illustrative and interesting uses of the LUSAS software on projects around the world.


Latest Software Release

  • LUSAS Version 15.0-3 - this is an error fix release that also includes a change to the IMDPlus software option, which now allows users to analyse the time domain response of a 2D or 3D structure to the passage of a moving vehicle or train, where spring-mass systems are used to define the configuration of the vehicle. Software was uploaded on 8 July 2014.
