LIRA-FEM 2024 R1 Update 1

Last updated: January 25, 2024

  • Refined calculation of the stress-strain state in iterative nonlinear solids with the specified concrete and reinforcing materials.

  • Fixed bug: possible failure of the program when the boreholes were added.

  • Fixed bug: possible failure of the program when a design model that contains PRB was exported to a *.sli file.

  • Modified settings: measurement units for mosaic plots of pile pressure on soil.

  • Modified mosaic plots: the output data for individual check of steel beams with a channel cross-section.

  • Modified visualization: rotation of metal cross-sections.

  • Restored speed of pile calculation by the model of equivalent pile foundation.

  • Modified encoding for some characters in the temperature distribution table generated in *.csv format.

  • Fixed bug: the warning messages were duplicated when the standard stiffness types were modified in group.

  • The "METEOR" system (Problem Integration): modified values of combination coefficients for the "Inactive" load type.

  • Restored option to open the nonlinear stress-strain diagrams for materials from the *.nll file.

  • For super-element problems, modified analysis and output of reinforcement for RC bars.

  • Modified selection of steel box cross-sections; clarified check for local buckling.

  • Fixed bug: may occur in check of deflections for steel beams calculated according to SP RK EN 1993-1-1:2005/2011.

  • In the analysis results of DCL(c), clarified DCL numbers displayed in standard tables.

  • Fixed bug: the behaviour of the "Copy Loads" dialog box when the Enter key is pressed.

  • Improvements in IFC import

    • Fixed bug: beam geometry was transmitted incorrectly.

    • Import of inclined slabs is enhanced.

    • For columns/beams with a steel cross-section, the "Steel Column/Beam" object is created and the "Steel Structures" material is automatically assigned.

    • Fixed bug: zero-length lines appeared in a project when the axes were imported.

    • Fixed bug: in changing the size of openings; it occurred when the model was saved for IfcDoor and IfcWindow object types.

    • Improved option to create the storeys by grid lines and/or slabs if storeys are not defined in the IFC file.

  • The work with the "Import IFC - Settings" dialog box is improved:

    • Fixed bug: the dialog box was closed when you switched to the "Materials" tab.

    • For objects that do not have an assigned material, on the "Materials" tab, the "not defined" line is now displayed and a default material may be assigned to such objects.

    • Added parameters for the "Geometric location of the site": X, Y, Z coordinates (m) and rotation angle (°).

  • Import KM: Fixed bug in creating an inclined slab in the physical model.

  • Import DWG: For objects generated along a closed contour, there is a new option to close the contour segment if the contour was broken in the original model.

  • Export IFC: Added option to export columns and capitals.

  • Updated plugin for Rhino 7 and Rhino 8.

  • Fixed bug: when the surface load is generated in the Node, the openings located inside the load were lost.

  • Enhanced tool for converting "Other" objects into a "Column" structural object.

  • Restored option to assign design parameters to steel elements when preparing a model.

  • Enhanced algorithm for uniting slabs with different thicknesses. When the command is activated, a new slab with thickenings is created.

  • New option to view links between loads and other objects.

  • Modified algorithm for generating a perfectly rigid body (PRB) between the column and wall objects.

  • Fixed bug: when an analytical contour above a wall was modified, the contour became an opening.

  • Fixed bug: in the "Parameters of Analytical Model" dialog box for stairs, restored option to assign a support to an asymmetrical part of a staircase if the "Symmetry of boundary conditions" option was enabled.

  • Fixed bug: when an opening was added to a slab, additional triangulation lines were not transmitted to the design model.

  • The "Eye-Drop Properties" tool is improved.

  • Fixed bug: properties assigned to piles were lost when a project file was saved or opened.

  • Fixed bug: incorrect functionality of the "Undo" command after the "Fill pattern for opening" command was activated.

  • Enhanced option to create a contour by segments (mode).

  • Fixed bug: (when copying a wall with assigned bar analogues) the stiffnesses of the bar analogues were duplicated in the VISOR graphical environment.

  • Fixed bug: in copying triangulation lines and points on the slab.

  • Fixed bug: when trusses were copied, the design parameters assigned to elements disappeared.

  • Fixed bug: the load on slabs was applied by a space that does not intersect them.

  • Fixed bug: in the properties of partitions, the assigned load cases were not saved when the meshed model was generated.

  • When bar analogues are created for walls with openings, the local Z1-axis is now oriented in the plane of the wall.

  • Fixed bug: tolerance parameters were duplicated in properties of the project.
