New LIRA 10.14 R3.0 version has been released
8/13/2024
Dear colleagues, we're informing about official release of a new SP LIRA 10.14.

SP LIRA 10.14 R3.0 is available for downloading in download section. Licence holders of SP LIRA 10.14 can update to 3.0 version for free.


Release 3.0 contains corrected detected errors and some changes and additions.

Graphics system and computational processor
  • In module (64) of seismic action calculation according to the standards of the Kyrgyz Republic the requirements set forth in SN KR 20-02 2024 have taken into account
  • A new spectral dynamics module (26) has been implemented to take into account the blast wave impact on design model
  • When assigning external dynamic loads for the system DYNAMICS+, an automatic generation of the blast wave impact graph has been implemented
  • For the finite elements of non-reflecting boundary (62, 64, 68) the possibility to specify the scaling pole (load application) which is necessary for static loading states has been implemented
  • New plate FE (122, 130) and solid FE (132-136) have been implemented to model the pressure on vessel walls and fluid splashing in static and dynamic problems
  • The possibility to assign a structural element to architectural bar has been implemented
