Structural engineering software LIRALAND Group
The stability of the program and the accuracy of calculations have been improved. Crash errors, as well as errors in load generation, errors related to erection stages, openings and complex geometry have been eliminated. The processing of dynamic problems has been optimised and the analyses for punching shear, steel and reinforced concrete sections have been refined.
The update delivers enhanced stability, improved data transfer between LIRA-CAD and LIRA-FEM, and refined algorithms for triangulation, load generation and collection, as well as handling of openings and complex geometry. The calculation core has been improved with more accurate thick plate behaviour, optimized processing of large time history analyses, and refined checks in accordance with DBN and EN standards, resulting in more reliable results and higher calculation accuracy.
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.
Modifications have been made to the functionality of creating and editing models, which contribute to improved accuracy. Configuration of calculation parameters and performance improvements. Integration of new algorithms. Bug fixes, comprehensive enhancement of the interface, security, and overall performance.
