This page contains list of changes, fixes and new features in FEM-Design 24.

Version 24.00.002

Released: 24th of February 2025

Added:

• The explanation note in the Connections tab of Profiled and Timber panel dialog was extended.
• HD-F 120-40 and 120-50 sections were added to the Hollow Core section library group.

Fixed:

CAD/System

• Unnecessary Close button was removed from the Documentation panel and the Calculation window of standalone Steel Joint module.
• Correct model/Merge region lines function did not work, if an edge connection belonged to any of the lines that should have been merged.

Input

• When distance parameter of surface connection was modified, the position of the interface region was not modified.
• If General material was chosen, the program could crash.
• Panel colour in Connection tab of Profiled and Timber panel dialog was not correct in some cases
• Bar end condition types were not pasted correctly, if the pasted model had different annex.
• Shell connections were not visible in the Filter menu when the shell was chosen first.
• Last row of the table was not seen at material's Plastic analysis data dialog in the Polish translation.

Loads

• Surface loads defined by their resultant were not considered correctly in the calculation, if they acted on a cover.
• Program could crash, when Import/Export Save as default was pressed at Load groups dialog.

Results:

• Program crashed in some cases when Filter was used to display connection force results

Design:

• Modifying or deleting bars after Steel or Timber design tab was entered might have caused crash at saving the model.

Documentation:

• Title block fields disappeared when any project data was modified in the Settings/Project/Title dialog.

Version 24.00.001

Released: 6th of February 2025

Added:

• An "All" button has been added to the Transparency tool window.
• Model name filtering option in the Input Wizard.
• Labels display the models’ name in the Input Wizard.
• A “Duplicate” window button on window tab bar.
• In timber bar fire design calculations, users can now specify whether solid and glue-laminated timber are considered as softwood or hardwood when using automatic nominal charring rate calculation.
• Offline crash viewer diagnostic tool.

Modified:

• The Correct model function no longer merges region lines that have an assigned edge connection or physical extension.
• Improved preview image sizing in the Input Wizard.

Fixed:

User interface

• The window list was duplicated when changing positions.
• Resolved a 1-pixel gap at the bottom of program window in Windows 11.
• Fixed flickering and overflow issues in the Colour schema dialog.
• When hidden buttons were made visible on the ribbon by "Show hidden buttons" option, they were not faded as in earlier FEM-Design versions.

Graphic engine

• Symbols were displayed incorrectly unless the graphics engine was set to DirectX.
• Some texts disappeared from dimensions when using OpenGL with a non-white model background.

CAD/System

• Number of selected objects was not displayed correctly in some cases.

Input

• The behaviour of Connections and Connected objects functions was confusing and has been improved.

Loads

• After generating load combinations, duplicate instances of the same combination could appear.
• In the traffic load result view, internal force or stress results could be incorrect at bar ends.

Foundation design

• Soil pressure calculations were incorrect in some special cases.

RC bar design

• Selecting a section with a different number of edges than the original section caused a crash later in the process.

RC shell design

• Scaling of Single shell reinforcement did not function correctly.

RC punching design

• For German Annex, C,Rd,c calculation for punching was incorrect.

Steel design

• The buckling curve for lateral torsional buckling was not chosen correctly in certain cases when "Use EN 1993 - 1-1:6.3.2.3 for NA specified sections" option was selected.
• The auto-design of steel bar shell models did not correctly determine thickness values in some special cases.
• The scrollbar size in the Detailed result window was incorrect in some cases.
• In steel bar design calculations, the interaction check did not take into consideration for which internal force was the section classified as Class 4.

Steel joint design

• In beam-to-beam joints with welded splice plates with 2 or 3 welds, the width of the gap was not checked.

Timber design

• Principal axes were not displayed in Timber bar detailed results.
• Some design changes did not affect structural data (e.g. timber fire design), yet an unnecessary dialog appeared about applying changes. This dialog has been removed in such cases.
• Some controls were missing from Buckling length tool window for timber bars in certain situations.

Composite design

• In composite column design, the calculation of N,pl,c,Rd did not include α,cc.

Results

• Resultant arrows for Reaction/Connection result were not displayed, when the Graphic engine mode was set to OpenGL.
• Resultant arrows for Reaction/Connection result could disappear when scaling or rotating the model view.
• In the Detailed results for line reactions for maximum of load combinations, the corresponding load combination was not displayed correctly.

Documentation

• User-defined filters were not listed in the Tables/List of objects dialog.
• In Detailed results, certain notations (e.g., minimum and maximum reinforcement check conditions) may have been misleading, implying that the checks had already been performed and failed. This has been clarified. The relevant chapter titles have been supplemented, and misleading conclusions have been removed.

IFC

• Various bugs were fixed, and minor improvements were made to IFC export and import.
