In Tekla Structures it is possible to generate analysis model that includes bars, plates, loads and boundary conditions. LIRA-FEM program supports two-way integration with Tekla Structures.


Step-by-step guide that describes the full cycle of building design, namely creation of architectural model, its conversion into an analytical model, analysis and design, issuance of design documentation by using LIRA-CAD and LIRA-FEM software packages.


Step-by-step guide for novice users of the LIRA-FEM software, which reveals the basics of finite element analysis.


Rhino/Grasshopper and SAPFIR module will interact directly through this plugin to create and edit the BIM model. It may be done with Grasshopper visual script interface. The live and associative interaction allows the user to create projects of different complexity.


Within the framework of building information modeling (BIM) concept, two-way integration of Autodesk Revit - LIRA-FEM - Autodesk Revit is implemented.


The construction of finite element meshes is an important stage of solving the problem of determining the SSS of structures. This stage is associated with satisfaction of a number of contradictory requirements.


LIRA-FEM plugin in Revit helps our users to transfer model directly to LIRA-FEM or via SAPFIR, perform analysis and return reinforcement results back in Revit.


In this video guide, we will export our project to LIRA-SAPR, analyze scheme and import results of reinforcement to LIRA-CAD.


Accounting of earthquake effect assumes that the structure resists passively through the combination of strength, deformation and energy absorption. The damping level of such a system is usually very low and therefore the energy dissipation value of such a system in elastic behavior is also low. During the strong earthquake the def...

The LIRA-FEM version 2025 will use a different protection from Wibu-Systems AG, a German business. The page provides setup instructions for the CodeMeter network license server along with general details about key types.


Suppose we have to make the automatically generated PR types come from the LIRA-CAD module to the LIRA-FEM program; in these PR types, the reinforcement pattern is arranged in two layers.


This paper explores two main methods of running LIRA-FEM on a Mac: virtualization through Parallels Desktop for M-series processors and using Boot Camp for Macs with Intel processors. We will go over the benefits and drawbacks of each approach. Finally, we'll include a detailed installation tutorial for LIRA-FEM using Parallels...
