General LUSAS software information

Notification and downloading of the latest release version of LUSAS

  • LUSAS 'Licence key', 'Technical' contact(s) and LUSAS users in your organisation, for whom we have an email address, are notified of the availability of each new LUSAS software release.

  • LUSAS recommends that the latest software version is installed and used as soon as it becomes available, but we appreciate that not all clients will want or necessarily need to upgrade its users with each new release. As such, we provide 'What's new?' links to allow clients to decide if it is immediately relevant to them.

  • LUSAS software is made available for download as a single ISO file, or as a web installer executable. 

  • A DVD can be requested by those who cannot or prefer not to download the software.

LUSAS licence keys

  • If you require a new network license key please contact licensing@lusas.com prior to installing the software. If possible please state  the Name of your organisation and your LUSAS Key ID. If not known, the Key ID can be obtained from running your existing version of LUSAS and selecting Help > About LUSAS Modeller > Key Information.

Request a LUSAS Software DVD

  • If you wish to be sent a DVD instead of downloading this software please email updates@lusas.com stating the Name of your organisation and your LUSAS Client (KeyID) Number. If not known, this can be obtained from running LUSAS and selecting Help > About LUSAS Modeller > Key Information

LUSAS software releases and compatibility

  • 'Major' releases of the software (such as V21.0 and V20.0 etc) represent a substantial new release containing major new functionality, potential changes to model or data formats, and general error fixes.

  • 'Minor' 'Point' releases (such as V21.1 or V20.1 etc) are normally used when general new facilities and improvements are introduced. Point releases will also contain error fixes made to a previous software release, and may also contain changes to model or data formats.

  • 'Dash' releases (such as (V21.0-1 or V21.0-1) are (generally) used when only error fixes have been made to a previous 'Point' release.

  • LUSAS model and results data can only be read in a particular version when it was written by a version with the same or lower 'major' version, and also the same or lower 'point' release version.


LUSAS releases prior to Version 16

  • Please contact LUSAS technical support to obtain download details for software releases prior to LUSAS version 16.
