This page contains list of changes, fixes and new features in FEM-Design 22 service versions.

Version 22.00.003

Released 18th of May, 2023


  • Fix: Merge region lines function of Correct model tool caused crash if the region had more holes with different numbers of sides.


Version 22.00.002

Released 19th of April, 2023


  • Composite design / Auto design / Circular symmetry option is available for Circular cross-sections.
  • Design group definition is added to FDscript.
  • Cmdinteractionsurface command is added to FDscript.
  • Entity selection to cmdlistgen command is added to Fdscript.
  • From now the maximum number of construction stages is 499 instead of 99.
  • Punching reinforcements can be exported to Allplan.
  • RC Design / Punching / Calculation parameters / Automatic Beta factor calculation is supplemented with a punching region's principal direction-based method, which is more conform with the EN 1992-1-1 6.4.3. (3).
  • Hungarian language version is updated with FD22 features.
  • Polish language version is updated with FD22 features.
  • Dutch language version is updated with FD22 features.

  • Bar utilization lists header include material type.
  • Composite design / Design: Circular symmetric reinforcement alignment was made available for Circular sections.

  • During struxml import reinforcement bars were created in non-uniform RC bars.

  • If "Custom" load combination method was at least once selected, the resulting disabled checkboxes in the "Generate load combinations" dialog maintained their status regardless of which load combination method was chosen afterward.
  • If a model containing extremely many load combinations was pasted program slowed  down.
  • If calculation failed after design changes were applied on the model, invalid results were listed in the Result tree.
  • In case of plastic steel beam non-linear analysis during scaling of load combination results, there was a problem under certain circumstances.
  • In case of steel bar-shell model calculation relevant buckling modes were not correctly initiated in some cases.
  • In RC shell calculation parameter dialog design eccentricity parameter modifications were not saved.
  • In some cases the Esc and error handling was wrong during bedding modulus calculation.
  • In some rare cases RC bar auto design didn't work for longitudinal reinforcement.
  • In Steel bar design detailed result dimension lines were placed too far from the sections in certain cases.
  • In the Correct model dialog after loading settings the statuses of buttons were not refreshed.
  • In timber bar detailed result the equation for  k_m,alpha  calculation was not displayed correctly in some special cases.
  • In timber design calculation of LVL and Kerto beams depth and length factor was not taken into consideration if the beam size was bigger than the reference depth/length.
  • Incorrect fire exposure data caused crash in RC bar design calculation.
  • Listing launched from the Quantity estimation dialog did not contain all objects that were in the dialog.
  • Load combination results are exported to Idea StatiCa.
  • Load group combinations table did not highlight selection.
  • Load tab / Construction stages could be deleted by Model space / Erase function using CTRL+A.
  • Loading files made in FD21 may have caused error at saving to StruXML format, if the model contained shear reduction zones.
  • Material and section of bars imported via IFC were not compatible in some cases.
  • Modification of bar properties deleted general steel joints connected to the modified bars in some cases.
  • Modification of Soil/Filling level point caused crash in some cases.
  • Modifying the properties of a bar that was connected to a General joint caused crash in some cases.
  • Nodal Shapes have wrong NodeId at listing table:  Imperfection/Stability.
  • Object type conversion did not preserve the construction stage of the object.
  • Picture colour were not correct in Documentation module, if OpenGL graphic engine was chosen.
  • Piles unnecessarily increased memory usage during RC bar design.
  • Potential crash on DWG import using layer names that clashed after losing international characters.
  • Pre-calculated cross-section data that speed up calculation were not generated during cross-section import in some cases.
  • Pressing Undo in the documentation module caused crash, if a tool was active in the graphical window.
  • Program may have crashed if structural objects were deleted after deflection calculations.
  • Property change of RC bar reinforcement macro for concealed bars caused crash.
  • RC bar auto design was over-reinforcing for torsion in some cases.
  • RC bar auto design caused crash in some special cases.
  • RC bar reinforcement macro was not placed on the correct layer.
  • RC Design / Punching / Nodal force calculation method is incompatible with seismic effects and 2nd order analysis, therefore shell internal force-based solution is applied in these cases.
  • RC Design / Punching / Shell internal force is calculated on the analytical plate instead of the physical, consequently smaller internal forces are at edge/corner punching.
  • RC Design / Punching / Shell internal force method could rarely calculate higher punching forces using Max options.
  • RC Design / Punching: Automatic punching region generation is more permissive for overlapping bars.
  • RC shell calculation for Result points caused crash in some special cases.
  • reinforcements of composite columns could not be exported to Allplan.
  • Shear check was not calculated correctly for some delta-like steel sections.

  • Single row deletion in load group combination table is now available.
  • Some types of Custom result were not displayed correctly in Plate module, if the model contained columns.
  • Some warning message of steel bar design calculation did not refer to the correct load combination.
  • Steel bar shear check was not displayed correctly in the detailed result of the design group.
  • Steel design / Check using Max of Load groups, the sections could be shifted by 1 step in rare cases.
  • Steel joint tool contained "Set master member" option unnecessarily and pressing it caused crash.
  • Stiffness calculation of beam-column steel joints with end-plate was not correct if all tension bolt-rows were outside the beam's flanges.
  • TDA material settings could be lost using multiple selections.
  • The checking of intermediate cross-section was not correct in case of variable cross-section bars.
  • The finite element mesh statuses were not handled correctly if mesh had to be adjusted to assigned loads. This caused different types of bugs in mesh creation and handling in some cases.
  • Timber bar fire detailed result crashed if it was to be displayed for non-accidental load combination.
  • Too short reinforcement bars may have caused crash in RC bar manual design mode.
  • Web buckling check for non-uniform steel bars was not calculated correctly.

  • The value of k_def (deformation factor) for characteristic (Sc) combinations is set to zero by default.
  • In Composite design, Section utilization imperfection consideration in the second order moment has been changed with distinct k value using EN 1994-1-1 formula 6.43.


  • Axis labels with prefix contained  an unnecessary grey arrow.
  • If axis prefix was modified, its position number was also modified.
  • Assigned load is now adjusted to the structural object after its geometry was modified.
  • Some tooltips in the Load group dialog was misplaced.
  • Changing the type of fictitious bar could cause a crash.
