• Added the option to assign linear heat‐technical characteristics to materials, with their subsequent export to the 15th model type.

• Calculation of the sectional moment of resistance of the cross-section has been added to the characteristics table.

This module now offers the new option to export files to the 15th model type in the LIRA-FEM software. This feature allows the user to quickly generate design models for the problems with heat transfer analysis. During the export procedure, the proper finite element types and stiffnesses are assigned to all elements; convective heat transfer elements are moved along the outer contour of the section to simulate boundary conditions and external loads.

When the geometry is exported from *.dxf file, the arcs and segments that have matching ends in the *.dxf file are now included in the same contour.
