Introduction
LUSAS is one of the world's leading structural analysis systems. By choosing to use
LUSAS you are joining a large worldwide community of engineers who use LUSAS
everyday to solve a wide range of engineering analysis problems.
Before starting to use LUSAS it is strongly recommended that you read this Getting
Started Guide in its entirety. It provides an essential overview of the LUSAS Modeller
user interface and of the processes involved in creating models, running analyses and
viewing results. The guide also lists the LUSAS documentation available for you to use
and provides information on additional resources including how to obtain technical
support.
About LUSAS
The LUSAS system uses finite element analysis techniques to provide accurate
solutions for all types of linear and nonlinear stress, dynamic, and thermal/field
problems. The two main components of the system are:
 LUSAS Modeller - a fully interactive graphical user interface for model
building and viewing of results from an analysis.
 LUSAS Solver - a powerful finite element analysis engine that carries out the
analysis of the problem defined in LUSAS Modeller.
The Application Products
LUSAS is made available as different application products with the user interface
tailored specially to the needs of a particular application. For example bridge engineers
will see facilities provided specifically for the analysis of bridge structures. Such
facilities are normally conveniently grouped together inside a product application
menu, such as Bridge, Civil, Composite etc, that is loaded between the Utilities and
Window menu items in the main menu.
Academic users have the choice of which application product they would like to use.
When starting LUSAS Modeller an additional dialog offers this choice.
1
Getting Started Guide
The application products include:
 LUSAS Bridge – for bridge engineering analysis, design and assessment.
 LUSAS Civil & Structural – for civil, structural, nuclear, seismic,
geotechnical and offshore engineering.
 LUSAS Analyst – for automotive, aerospace, defence, manufacturing, and
general engineering analysis.
 LUSAS Composite – for engineers designing composite products or

Using LUSAS - An overview
Carrying out an analysis with LUSAS will involve three main stages:
 Modelling
 Running the analysis
 Viewing the results
Modelling is sometimes referred to as ‘pre-processing’ and viewing and manipulating
the the results is sometimes referred to as ‘post-processing’. Further details of these
stages are provided below.
Model Types
Two types of model can be created in LUSAS:
 Feature-based geometry models these are based on features (such as points,
lines, surfaces and volumes) that are defined inside LUSAS, or are created from
imported geometry and require the definition of mesh objects such as elements
with their associated nodes.
 Mesh-only models - these comprise only mesh objects (elements and their
associated nodes, edges and faces) and are created by importing only those
types of LUSAS model data, or third party data that are supported.
With very few exceptions the majority of LUSAS models are featured-based.
Modelling
Modelling involves creating a geometric representation of a structure and defining its
characteristic behaviour in terms of its physical properties such as material, loading,
and support.
3
Getting Started Guide
 Geometry
Within LUSAS Modeller the geometry of the model is defined using points,
lines, surfaces and volumes. A volume needs surfaces to enclose it and to define
its boundary. Similarly a surface needs lines to form its perimeter and lines
need points to define their ends. The shape of a surface between its boundary
lines, and the shape of a line between its end points can be simple (straight
lines, flat surfaces) or complex, depending on the manner in which it was
created.
Many different tools exist within LUSAS Modeller to aid the creation of
geometry. In particular the geometry can be entered numerically, in terms of
coordinates, by cursor (using the mouse) or by copying, splitting, intersecting
and transforming previously existing parts of the model. Geometry can also be
imported from third-party interface files.
 Meshing attributes
Whilst points, lines, surfaces and volumes allow the geometry of the problem to
be represented or imported, to solve the problem, the geometric features must
be broken down into discrete nodes and elements. This process is known as
meshing and the collective term for all the elements and nodes, once created, is
the mesh. Special attributes, called mesh attributes, are created and assigned to
relevant geometry features to define the type and number of nodes and elements
that will be used to represent each part of the geometry.
A significant advantage of this approach is that the density of the mesh can
easily be changed without rebuilding the geometry or reassigning any attributes.
Simply modifying a mesh attribute automatically changes the mesh density in
any part of the model where it is assigned.
Similarly, the element type can be changed in exactly the same way. Different
element types are suitable for different kinds of analysis, and the system
provides an easy way to change from one to another.
Generally LUSAS Modeller automatically and incrementally updates the mesh
whenever a change is made to any part of the geometry or any mesh attributes.
However these automatic updates are not allowed when results are being
displayed, and they can also be switched off if at other times if required, for
example to save time. This is known as locking the mesh. When the mesh is
locked it will only be updated when specifically requested.
 Other attributes
Other attributes are used to define aspects of the behaviour of parts of the
model, or the external factors which are imposed on it. Within LUSAS
Modeller, there are several types of attribute such as materials, loading and
supports. Within each attribute type there may be further sub-divisions, for
4
Modelling
example there are isotropic materials, anisotropic materials, and orthotropic
materials, among others.
In each case an attribute is first created, and then subsequently attached to all or
selected parts of the model. This attachment process is known as assigning.
Thus a material can be assigned to a line. Once assigned, the line takes on the
properties of the material until further notice. Assignment often involves
specification of additional information that does not define the attribute or the
geometry, but rather defines how one is applied to the other. This includes
directions, scale factors and similar.
A special attribute, called a geometric attribute, is used when some or all of a
model is comprised of lines or surfaces. In this situation, LUSAS Modeller
needs to know the cross-sectional appearance and behaviour of lines, and also
how thick the surfaces are. Geometric attribute assignments provide this
information, and therefore form part of the model’s appearance. Models
comprised entirely of volumes do not need geometric assignments.
Many different tools exist within LUSAS Modeller to give interactive feedback
on the nature of assigned attributes. This process is generally termed
visualisation. Visualisation usually takes the form of coloured infills, arrows,
textual labels or similar.
 Analyses
Within a single model file any number of analyses may be defined. Each
analysis will inherit most of the assignments, options and settings of what is
called the base analysis for the model. Use of the multiple analyses facility does
away with the need to create separate models, or maintain “clone” copies of a
model, in order to switch between and create results from linear static analysis
and other analysis types.
 Loadcases
In a linear analysis, it is convenient to gather certain types of applied loading
together, if it is applied at the same. for example gravity and wind loading
which are applied at the same time. A loadcase is the term for such a collection
of loading. Each loadcase is solved separately and the results are available
separately. Results can be combined together during the results viewing stage if
required.
In a nonlinear analysis, LUSAS loadcases are equivalent to analysis stages.
Within each loadcase, the loading, supports, or type of analysis can be changed.
Control parameters can be set for each loadcase.
 Utilities
5
Getting Started Guide
Some kinds of analysis require or create extra data that is similar to attributes,
but cannot be assigned to geometry. LUSAS Modeller refers to such data as
utilities. Tendon profiles, reference paths and the settings made or entered to
plot a graph or produce a report, for instance, are all examples of utilities.
 Controls
Finally, for analyses other than simple linear static, it is sometimes necessary to
control the analysis process itself. LUSAS Modeller uses controls for this
purpose. Controls are either nonlinear, transient, eigenvalue or fourier in nature.
 Further Modelling Information
Browse the LUSAS Modeller interactive online help system, or see the
Modeller Reference Manual for detailed information about any of the above.
Running the Analysis
Once the modelling process is complete, the model is passed to LUSAS Solver for
analysis. LUSAS Solver will then create results that are automatically loaded back into
modeller for viewing and optional post-processing.
Viewing the Results
Results are available to be viewed in many different ways, and the results can, if
desired, be combined with attribute visualisation to make a plot, for example, that
shows the applied loading and the resulting deformations.

Worked examples
Worked examples
A large selection of tutorial examples are available to help you to get up to speed with
LUSAS and it is strongly recommended that you work your way through a selection of
the examples to get a feel for the system before starting on your particular problem.
See the Examples Manual and/or the Application Examples Manual(LUSAS Bridge
and LUSAS Civil & Structural).
The LUSAS Modeller User Interface
The image below shows the principal user interface components of LUSAS Modeller.
The View Window shows the model itself. Each view window is completely
independent and may show the model from a different angle, using different
visualization options, with or without results. The image in a view window is built up
from several drawing layers as listed in the layers panel in the Tree Frame. Each draws
over the top of the one before it. In the example shown, Window 2 draws geometry
first, then contours, then mesh, then annotation.
The Tree Frame has several tabbed panels each with its own Treeview showing a list
of objects of a particular type. In the example shown the attributes panel is front-most.
7
Getting Started Guide
Additionally there are panels of layers, groups, loadcases, utilities and reports. Each
object in a Treeview has its own functionality. This can be invoked using its own
context menu, the main menu or the toolbar buttons. In summary:
 The Layers
Treeview controls the display of selective model data and
results data to a view window.
 The Groups
Treeview is used to store selected user-defined collections of
objects (geometry, nodes or elements) under a collective name.
 The Attributes
Treeview contains information relating to the model; the
element type and discretisation on the geometry; section properties and
thicknesses; the materials used; how the model is supported or restrained; and
how the model is loaded.
 The Analyses
Treeview shows all analyses defined; loadcases defined
including analysis control loadcases defined during the modelling stage; results
loadcases containing solutions for results processing; loadcase combinations
and envelopes; and IMD and Fatigue calculations.
 The Utilities
Treeview contains utility items used in the definition of model
geometry or attributes, or to control an analysis, or to provide a particular
functionality, such as to define a load combination or produce a report for
example.
 The Reports
Treeview contains a user-defined folder structure of reports,
chapter and image entries to allow a report to be generated in a variety of
formats.
Datatips provide basic model information about whatever is under the cursor. Tool tips
report on uses of toolbar buttons or expected input for grid cells etc.
LUSAS provides continuous feedback in the Text Output Window. This includes
errors, warnings and progress messages. The contents of the Text Window should be
continuously monitored.
The Status Bar displays progress messages and help text during a modelling session,
the model units, the current cursor position in model units (if the model is displayed in
an orthogonal plane) and the item or number of items in the current selection.
The Browse Cyclable Items and Browse Selection windows (which can be optionally
added to the interface) are populated with feature names of a selection.
Pressing the right-hand mouse button with an object selected in the View Window
usually displays a Context menu which provides access to relevant operations. In
addition, most items in the various Treeview panels also have a context menu which
provides access to additional functionality such as editing of data, control of visibility,
visualisation of assignments, and selective control of results plotting on selected
attributes.

Documentation Available
General notes
Within each View window, and within each Treeview, there is a current selection. In a
Treeview there can only be one object selected at a time, and all commands are
assumed to apply to it. In a View window several objects can be selected at the same
time. Main menu and toolbar commands apply to whichever window was most recently
clicked, either a View window or a Treeview panel.
Selected items support drag and drop functionality. Typically this will move them,
copy them or connect them together. For example, dragging an attribute from the
Treeview onto a View window assigns the selected attribute to the selected object in
that window.
All the menus, toolbars, tree frame, text window, status bar and other similar windows
can be resized, moved, made visible or invisible, and docked or separated from the
main program window. LUSAS Modeller will remember their new location for the next
time the program is run. Additional customization is possible - see the Modeller
Reference Manual for details.

LUSAS Product Options
In addition to LUSAS software being provided as particular individual application
products, product options are also available which extend the analysis capabilities of
these products. Product options can be made available for use by the supply of an
12
LUSAS Product Options
appropriate security key that 'unlocks’ the product option, allowing immediate access
to the extended facilities in your currently installed software. If your current license
doesn’t support these product options then please contact your LUSAS supplier to find
out how you can gain access to them.
The following software options are available for all products:
 Fast Solvers - This option includes additional solvers. The Fast Multifrontal
Direct Solver can provide solutions several times faster than the standard
Frontal Direct Solver for certain analysis problems. The Fast Multifrontal Block
Lanczos Eigensolver can, similarly, return results several times faster than the
standard Frontal Eigensolvers for certain problems. The complex eigensolver
provides efficient solutions for large-scale damped natural frequency problems.
 Nonlinear - Nonlinear stress analysis is becoming increasingly important with
designers employing a wider variety of materials in a multitude of different
applications. The Nonlinear option, rightly regarded as the leader in nonlinear
analysis, provides the very latest powerful techniques for solving problems
having either material, geometric or boundary nonlinearity.
 Dynamics - Straightforward modal dynamics problems can be solved using
Interactive Modal dynamics (IMD) techniques provided in all LUSAS products.
The Dynamics Option contains the facilities required to solve a wider range of
dynamic problems in both the time and frequency domains. By combining the
Dynamics and Nonlinear options both high and low velocity nonlinear impact
problems can be solved using either implicit or explicit solution techniques.
 Thermal/Field - The Thermal / Field option contains extensive facilities for
both simple and advanced steady state, and transient thermal / field analyses.
By combining the Thermal / Field option with other appropriate options, heat
transfer due to conduction, convection and radiation can be analysed. In
addition, the effects due to phase change of material may also be included.
 Heat of Hydration - Allows modelling the heat of hydration of concrete. The
heat of concrete hydration can be computed during a thermo-mechanical
coupled analysis and the temperatures and degree of hydration can be read into
a structural analysis.
 IMDPlus - The IMDPlus option extends the Interactive Modal Dynamics
(IMD) techniques provided in all LUSAS products. Whilst IMD models a
single loading event in a single direction, IMDPlus allows multiple loading
events with more advanced loading conditions to be solved. IMDPlus is used
for three primary uses: Seismic response analysis of structures subjected to
acceleration time histories of support motion; moving load analysis of
structures, such as bridges, subjected to moving vehicle or train loads, where
the magnitude and configuration of the loading remains constant throughout the
analysis; and moving mass analysis of structures, such as bridges, subjected to
moving vehicle or train loads, where spring-mass systems are used at the
axle/bogie positions of a vehicle.
13
Getting Started Guide
The following options are available for LUSAS Bridge only:
 Vehicle Load Optimisation - The Vehicle Load Optimisation facility
incorporating the well-known Autoloader software complements and extends
the vehicle loading capabilities of LUSAS Bridge and helps to simplify the
evaluation of worst load position for various load configurations. Vehicle load
optimisation is used to identify critical vehicle loading patterns on bridges and
apply these loading patterns to analysis models. It reduces the amount of time
spent generating models and leads to more efficient and economic design,
assessment or load rating of bridge structures.
 Steel and Composite Deck Designer - carries out comprehensive calculations
for multiple sections on steel or steel/composite bridge decks to the Eurocodes
 Rail Track Analysis - The Rail Track Analysis option permits track/bridge
interaction analysis to the International Union of Railways Code UIC 774-3. It
allows you to automatically build models from data defined in MS Excel
spreadsheets, run an analysis, and quickly produce results in spreadsheet or
results file formats.

Technical Support
Avoiding and Identifying Problems
A team of engineers in LUSAS Technical Support is available to all clients who have a
current support and maintenance contract, to provide modelling advice and assistance
with any problems that may be encountered. However, to identify the cause of a
problem may take time, especially if the analysis is large. Therefore preventative
measures should always be taken in an effort to avoid problems in the first place.
14
Technical Support
1.
Your analysis model should be thoroughly checked against intended data input
to verify that all geometry, attributes and assignments have actually been input
correctly.
2.
Read and follow the advice in the Pre-Analysis Checks and Post-Analysis
Checks sections of the Running an Analysis Chapter of the Modeller Reference
Manual. It is always good practice to systematically carry out these checks as a
matter of course whether or not problems are encountered.
3.

Additional examples may also be made available from the Support area of the LUSAS
web site.
