🚀 What’s New in LUSAS Academic 24.0-1

Version 24.0-0 (major release – July 2026) introduced a wide range of new facilities and enhancements.
Version 24.0-1 (September 2026) refined the software with targeted bug fixes, performance improvements, and greater reliability.

🔧 Advanced Modelling Enhancements

• New Cable (catenary) and Cable (Ernst) elements with dedicated Cable shape attributes for accurate modelling of sagged cables using unstressed length, maximum sag, or target tension.
• Significantly improved activation and deactivation control for joint and interface elements.
• Single-feature assignment of joints and interfaces — ideal for clean soil-structure interaction modelling without the need for coincident geometry.
• Enhanced pile and rock anchor modelling by embedding beam or bar elements directly into continuum models with realistic slip behaviour.
• New bond-slip modelling based on the CEB-FIP model code and Popovic model for more accurate reinforced concrete crack-width and ultimate load predictions.
• FCM Wizard improvements allowing bridge models to be generated along any alignment using a reference path.

📐 Design Code & Engineering Enhancements

• Full design of bonded post-tensioned prestressed concrete structures to Eurocode 2 (ULS and SLS checks in one workflow).
• Concrete frame design and RC Slab/Wall design now support AASHTO LRFD 10th Edition.
• Multiple reinforcement layers supported in RC Slab/Wall design.
• Updated creep and shrinkage material models for AS5100.5-2017, NZS3101:2006, and new support for CSA S6:19.
• Faster steel frame design calculations for CSA S6-14 and S6:19 codes.

🌉 Vehicle Load Optimisation & Bridge Analysis

• Improved carriageway definition and visualisation (including divergent carriageways, variable lane widths, and traffic direction).
• Full support for AASHTO LRFD 10th Edition and TRVINFRA-00331 (Sweden).

🌍 Geotechnical Analysis Tools

• New Soft Soil Material Model for highly compressible soils such as clays, clayed silts, and peat.
• Updated Modified Mohr-Coulomb (HS) model with improved convergence behaviour.

📊 Results, Combinations & Customisation

• Completely redesigned Smart Combinations & Envelopes facility with Eurocode-style leading and accompanying actions.
• Enhanced Graph Wizard with better location options, default axis titles, and unit control.
• Embedded Python interpreter included as standard for scripting and automation.
• Expanded Grasshopper plugin with new components.
• Official LUSAS GitHub repository containing practical LPI scripting examples in Python, VBScript, Jupyter, C#, and more.

🛠️ Bug Fixes & Stability Improvements in 24.0-1

Version 24.0-1 is a dedicated error-fix and modification release that resolves numerous critical, major, and performance issues. Notable improvements include:

• Fixed convergence problems with CEB-FIP bond-slip models under small loads.
• Significantly reduced processing times for models containing embedded interface bars.
• Resolved solver system errors related to temperature-dependent concrete material properties.
• Corrected behaviour of DMI Envelope attributes and Smart Combinations display.
• Multiple fixes related to vehicle load optimisation (VLO), graph results, design calculations, and overall stability.

These refinements deliver smoother performance and greater reliability for both day-to-day teaching and demanding research projects.

🎓 Academic Benefits & Interesting Facts

• No problem size limits on the full licensed Academic version — the exact same capabilities used by professional engineering consultancies worldwide.
• Free Teaching/Training version supplied with every order (limited to 200 points, 1000 nodes, 500 elements, and 20 loadcases) that can be freely distributed to students.
• Cloud-based Student Licensing available for individual students with valid academic email addresses (valid for up to 4 years).
• Extensive step-by-step worked examples and updated documentation specifically written to help students understand finite element fundamentals.
• LUSAS has its origins in research work begun at Imperial College London in 1970. The company continues to actively collaborate with universities and research institutions around the world.
• Special research interfaces and the LUSAS Programmable Interface (LPI) allow researchers to incorporate their own work and automate complex workflows.

LUSAS Academic 24.0-1 is the ideal finite element analysis software for engineering departments that want to equip students and researchers with modern, industry-standard FEA tools without artificial restrictions.

⭐⭐⭐⭐⭐ Excellent for Academic Teaching & Research

“LUSAS Academic 24.0-1 is outstanding for university use. The new cable modelling, bond-slip features, and AASHTO 10th Edition support make it extremely relevant for modern bridge and civil engineering courses. No model size limits on the full licence is a huge advantage compared to restricted student versions of other software. Highly recommended for engineering departments.”
