Update 1 for LIRA-FEM 2025 R2
The update delivers improvements to IFC import, model and load processing, enhanced interaction algorithms, and higher calculation accuracy. New geometry-editing tools have been added, Ukrainian steel tables for 2025 have been updated, stability has been improved, and multiple critical issues across LIRA-CAD, LIRA-FEM, and related modules have been fixed.
The new version brings significant enhancements to modeling and analysis functionality. IFC import and data transfer have been improved, along with optimized interaction between LIRA-CAD, LIRA-FEM, and related tools. Algorithms for triangulation, wall–slab interaction, and automatic load assignment have been refined. New geometry-editing features have been added, and the generation of wind and spatial loads has been improved.
A number of critical issues have been resolved, including problems with saving models, copying levels, transferring loads, handling special elements, forming stiffness properties, and importing visualization components. Calculations for pile foundations, material stiffness parameters, reinforced concrete checks, and temperature effects have been improved.
Ukrainian steel section tables for 2025 have been updated and expanded. Dynamic analysis performance has been optimized, response spectrum generation has been refined, and interaction with the ReSpectrum module has been improved. Overall system stability, data integrity controls, and performance have been significantly enhanced.
