Company history

The origins of the company go back to 1970 when a group of research workers at Imperial College in London began work on the London University Structural Analysis System, - LUSAS. This team was led by Dr Paul Lyons who, in 1982, set up an independent company, Finite Element Analysis Ltd, which has grown annually in size since then.

With continuous development, our LUSAS software products have now become some of the most respected engineering analysis software packages available today.
