LUSAS Finite Element System Version

LUSAS Finite Element System Version, developed by LUSAS, is a comprehensive finite element analysis (FEA) platform for modeling, analyzing, and optimizing structures and components across civil, structural, bridge, composite, and general engineering disciplines. It combines an extensive element library with advanced solvers and intuitive pre/post-processing tools to handle everything from routine linear analyses to complex, highly nonlinear, multi-physics problems.

Key capabilities

• Modeling: Extensive element types (beams, trusses, shells, plates, membranes, solids, cables, springs, and contact interfaces), geometric nonlinearity (large deflection and strain), material nonlinearity (plasticity, cracking, crushing, creep, orthotropic and anisotropic behavior), and time-dependent effects.
• Analysis types: Linear and nonlinear static; modal, buckling, harmonic, spectral, and transient dynamic; thermal/heat transfer; coupled and staged construction analyses; soil–structure interaction and consolidation; moving and impact loads; prestress and post-tensioning.
• Meshing: Automatic and manual meshing with local refinement, mapped and free meshing strategies, and support for mesh quality assessment and adaptivity.
• Solvers and performance: Robust sparse and iterative solvers with parallel processing for large models and demanding nonlinear or contact problems.
• Interoperability: Imports and exports standard CAD and analysis formats (for example, STEP, IGES, DXF) to streamline geometry exchange and model setup; supports automation and customization through scripting and user-defined materials and properties.
• Visualization and reporting: High-quality contour plots, vectors, animations, and time histories; result envelopes and combinations; configurable output and reporting to support review and documentation.
• Verification and reliability: Broad verification example sets and consistent unit handling to support quality assurance and model validation.

Typical applications

• Bridges and civil infrastructure: Load rating, moving loads, staged construction, cable-supported systems, bearings, and expansion joints.
• Buildings and structures: Steel and concrete frames, slabs, shells, and walls under gravity, wind, thermal, and seismic actions.
• Composites and advanced materials: Laminate and sandwich structures with orthotropic or anisotropic behavior.
• Geotechnical and soil–structure interaction: Retaining structures, embankments, foundations, consolidation, and seepage-linked response.
• Energy, marine, and industrial: Offshore jackets, risers, pipelines, pressure vessels, and equipment subject to static and dynamic loading.

Benefits

• Handles routine to highly specialized analyses within a single, cohesive environment.
• Reduces modeling time and rework through strong CAD interoperability and efficient pre/post-processing.
• Improves confidence in results via robust nonlinear/contact capabilities and well-validated solution procedures.
• Scales from small studies to large, detailed models with parallel solver performance.
