) began work on the London University Stress Analysis System, "LUSAS". This team was led by Dr. Paul Lyons, who, in 1982, set up an independent company, Finite Element Analysis Ltd., to further develop, and subsequently market the software as a general purpose structural analysis system. In 1997, following the introduction of a range of specialist application software packages, the company, for awareness reasons, then started to trade under the LUSAS name.

Software

LUSAS software consists of a Windows-based Modeller, used for model building and viewing of results, and a Solver for carrying out an analysis. Four commercial application products cater for the following industries: * Civil & Structural - for civil, structural, nuclear, seismic, geotechnical and offshore engineering. * Bridge - for bridge engineering analysis, design, and assessment. * Analyst - for automotive, aerospace, defence, manufacturing and general engineering analysis. * Composite - for engineers designing composite products or components. For Universities, an Academic version which permits the running of any commercial LUSAS software product can be used for teaching and research use.
