Detailed Specification


  • The detailed specification for each product lists the main features and capabilities of each product.  

Compatibility of LUSAS software products

  • Model and results files created by a lower product (such as Analyst) can be viewed and edited by a higher product version (such as Composite plus). 
  • Model and results files created in a higher product can be opened for viewing or editing in a lower product version provided the model contains only those elements and analysis options supported by the lower product.
Compatibility of LUSAS Composite software release versions
  • LUSAS model and results data can only be read in a particular software release version when it was written by a version with the same or lower 'major' version (such as V14 or V15), and also the same or lower 'point' release version (such as V14.5 or V14.6).
