Engineering analysis + design software

Software Products

LUSAS finite element analysis software is available in LT, Standard or Plus versions dependent upon the software product. Each product is designed for use by engineers in particular industries.

  • LT versions are suitable for linear static analysis of structural frames and grillages. 
  • Standard versions of software are suitable for linear static and linear modal dynamic analysis using beam, shell and solid elements.
  • Plus versions allow for more advanced analyses to be undertaken and include an extended advanced high-performance element library.

The analysis capabilities of LT, Standard and Plus versions of selected LUSAS software products can be extended by using software options.

For Bridge Engineering

LUSAS Bridge software is used for all types of bridge design, analysis and assessment from simple grillages through to complex cable stayed and suspension structures. It has an unrivalled range of analysis facilities for linear static, fundamental frequency, seismic, dynamic, soil-structure interaction, large deflection, staged construction, creep, prestress, post tensioning and fatigue analysis.

For Structural Engineering

LUSAS Civil & Structural software is used on all types of structures from buildings, grandstands and towers through to dams, docks and tunnels.It has comprehensive facilities for all types of civil and structural analysis including linear, nonlinear, staged construction, soil-structure interaction, creep, prestress, post tensioning, seismic, blast, buckling, impact, fire and fatigue analysis.

For Storage Tank Analysis and Design

LUSAS Tank allows engineers to automatically create a range of 2D and 3D finite element models of above ground full containment concrete or double-walled steel circular tanks from user-defined data. From these models, a range of staged construction, thermal, sesimic and other analyses can be performed, with design checks optionally carried out for specified load combinations.

For Composites Engineering

LUSAS Composite has advanced shell and solid composite elements for all types of composite engineering. It allows easy definition and visualisation of layups, and accurate delamination and failure modelling using a variety of industry standard failure criteria.

Available only as:

LUSAS Composite plus

To accurately predict the distortion of laminated composite parts during manufacture and provide reverse engineered surfaces to create "right first time" tooling LUSAS offers a consultancy service using its specialist LUSAS High Precision Moulding (HPM) software product. 

See LUSAS HPM Consultancy Service for details.

For Mechanical Engineering

LUSAS Analyst is used in the automotive, aerospace, defence, manufacturing and general mechanical industries. It is used for general engineering analysis and has highly regarded nonlinear and contact capabilities for solving all types of linear static, nonlinear, dynamic and thermal engineering problem, including thermal/mechanical coupling.

For Academic / Research Use

LUSAS Academic is for use only by educational establishments for teaching purposes and research. By using the software protection device and licence key supplied, the full licenced version allows access to any LUSAS commercial product, and access to most LUSAS analysis software options, with no restriction on model size.

Available only as:
