Dear colleagues, we're informing about official release of a new SP LIRA 10.12.

Release 2.3 contains corrected detected errors and some changes and additions.

SP LIRA 10.12 R2.3 is available for downloading in download section.

Licence holders of SP LIRA 10.12 can update to 2.3 version for free.

Graphics system and computational processor
  • Possibility to specify up to 1000 loadings has been restored
  • Accounting of non-reflecting boundary elements (62,64,68) in a linear problem DYNAMICS+ using the ASSEMBLAGE system has been fixed
