  • Individual links to worked examples provided in PDF format.

An index of all available documentation for this version is available here.

Software requirements

The LUSAS software version, software product (and version of that product) and any product options that are required in order to run an example will be stated in a usage box at the beginning of each example like this:

For software version: 19.0
For software product(s): All
With product option(s): Nonlinear, Dynamics, Thermal etc.
Note: This example exceeds the limits of the Teaching and Training version

Notes

  • Unless otherwise stated all examples listed and all associated files required are provided as part of a LUSAS installation.
  • LUSAS Analyst or LUSAS Composite products can run bridge or civil examples if a LUSAS Bridge or LUSAS Civil product option has been purchased.

  • LUSAS Composite examples can be run in any software product if a Composite product option has been purchased.

  • The LUSAS Academic software product will run any example, provided the correct product option is selected during start-up.

  • Examples that cannot be run using the Teaching and Training version of LUSAS (which has restrictions on problem size) are noted in the usage box at the beginning of each example.

For more information please download and read the Introduction to the LUSAS worked examples.
