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 startup.

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
