LUSAS Analyst / Analyst Plus Overview

wheel hub analysisLUSAS Analyst contains a comprehensive range of unrivalled engineering analysis facilities to cater for all types of engineering design.

From simple 2D linear analysis of beams and plates through to advanced 3D nonlinear shell and solid modelling, LUSAS Analyst will help shorten your design and checking times giving reliable results every time.

An intuitive Windows-based graphical user interface gives easy access to the full range of powerful modelling and results processing facilities, together with on-line help.

Regarded as a leader in engineering analysis, LUSAS Analyst is rich in powerful and advanced features to meet your analysis needs and extend your design capabilities.

Some illustrative uses of the software can be seen by visiting our engineering case studies page.


Ideal for everyday analysis

LUSAS Analyst comfortably meets your everyday analysis needs. Unrivalled state-of-the-art element libraries and material models allow all types of engineering problem to be solved. Metals, plastics, foams, and rubbers can all be modelled. Isotropic and orthotropic models are available for linear static, linear buckling, and fatigue analyses plus natural frequency analysis for determining mode shapes.


Better results in less time

Error contours for initial mesh and after 2 adaptive iterationsLUSAS Analyst lets you do more in less time. All models are created with built-in associativity allowing rapid design changes to be made. Automatic meshing is available and user-defined mesh arrangements are easily created. GUI results processing facilities allow extensive contouring, graphing and plotting for rapid interpretation of results.

Advanced analysis and design

Unlike some systems, LUSAS Analyst goes well beyond your everyday analysis needs. Advances in technology require advanced software solutions. LUSAS Analyst offers these solutions now to give you the edge over your competitors.

  • An easy upgrade from LUSAS Analyst to LUSAS Analyst plus and associated options gives an extended element set, additional material models, Fast Iterative Solver Technology and access to advanced analysis capabilities.
  • A software key system means that you can call us at any time for a key to unlock these powerful facilities so that you can tackle new analyses straightaway.

Fully customisable

By using the advanced scripting language, user-defined menus, forms and wizards can be added allowing specific repetitive analysis tasks to be performed with a minimum of user involvement. Complete analyses from modelling to results processing can be automated - and all tailored to your way of working.

Comprehensive nonlinear analysis

LUSAS Analyst is also rightly regarded as the leader in nonlinear analysis with superior problem solving capabilities. Powerful facilities for geometric, material and boundary nonlinearity are available for problems involving large deformations, plasticity and collapse. Fully automatic load incrementation, automatic recovery from convergence failure and restart features are all designed to enable newcomers to nonlinear analysis to quickly become proficient in solving a wide variety of nonlinear problems. Results processing facilities provide automatic load-displacement graphs and viewing of yielded material.

Impact and contact analysis

For low or high speed impact and contact problems LUSAS Analyst leads the field. Contacting elements are automatically detected and specially developed ‘slidelines’ and ‘slidesurfaces’ handle the interaction that takes place at contacting regions, greatly simplifying your analyses in 2D or 3D.

Dynamic analysis

Forced response, vibration and transient dynamic analysis problems can be solved quicker with LUSAS Analyst and, if you wish, by calculating the response for selected loadcases using the Interactive Modal Dynamics (IMD) results processing facilities. This gives shorter analysis times and reduced disk usage compared to a full transient dynamics assessment

Thermal analysis

LUSAS Analyst has a powerful set of thermal elements and extensive facilities for both simple and advanced, steady state and transient thermal analyses. Problems involving heat transfer due to conduction, convection and radiation can all be solved. Effects due to phase change of material can also be considered. If material properties are significantly affected by temperature distribution then a semi-coupled thermal/mechanical analysis can be performed. Changes to the component shape can also be accommodated by a fully coupled analysis.

Fatigue analysis

LUSAS performs fatigue calculations on the results of a linear finite element stress analysis using the total life approach. The fatigue life may be expressed in terms of the damage that is done to the structure by a prescribed loading sequence or as the number of repeats of the sequence that will cause failure of the structure. Contour plots illustrating the fatigue life of every part of the structure can be generated. More details

Working from CAD data

Model information can be exchanged with a wide range of CAD systems using industry standard exchange formats such as IGES and DXF, as well as directly with specific CAD systems using proprietary data exchange formats.

Software products

LUSAS Analyst is available in two software levels; Analyst, and Analyst Plus to suit your analysis needs. Each uses the same Windows user interface for easy and rapid model generation, load application and combining of loadcase results.

  • Both product levels use the same user interface and terminology, so training costs can be minimised and users can be introduced to LUSAS at the most appropriate level for the work they need to do. 

  • There is also full data compatibility across the products allowing easy migration of a model to a more advanced analysis when required without any data conversion or remodelling.

  • Separate details list the capabilities of each particular software product.


  • Use Analyst for linear static and linear modal dynamic analysis of beam, shell and solid models. 

  • Use Analyst Plus for more advanced analyses using the appropriate purchased option(s).
