The latest version of Advance Design brings a great number of changes and enhancements in many fields of the program. One of the most visible changes are improvements related to the speed of computation and the way data is stored. This short article will show the impact of these changes.

Description of changes

To help increase productivity time in Advance Design, we have worked hard to improve several areas, which translate into much faster calculation times, as well as reduced file sizes of the results.

Three areas have been changed:

  • Improvement of the calculation solver and program architecture

These changes consisted in the optimization of operations, thanks to which the speed of the FEM calculations has been increased.

  • Changed the way results for combinations are calculated

Previously, the results for each linear combination for each node were determined and saved to a file during the calculation. Now the results are calculated while displaying the results, which has dramatically reduced the size of the project on disk as well as significantly reducing the computation time. At the same time, the increase in the generation time for graphical results is unnoticeable.

  • Optimization of verification procedures for steel and timber elements

These changes concern the design procedures for steel and timber linear elements, resulting in a significant reduction in design time. Although some changes and improvements are common to all standards for steel and timber design, special attention has been given to design procedures for members according to Eurocode 3 and 5.


Below are 5 examples that illustrate the changes between the current and the previous version of the program regarding FEM calculations, steel/wood design and the weight of the result files.

 The average increase in performance

The above models represent an approximate range. However, the effect is global and independent of the nature and size of the model. The table below, shows the aggregate results for the decrease in the required time, as well as the decrease in size of the project file compared to the previous version of the program for a sample of 15 various models of different sizes and computational range.

Note that the above values are averaged and may vary depending on the number and type of elements, the number of load combinations and the type of analyses performed. The smallest impact of changes is seen on smaller structures with a small number of combinations but complex types of analysis (for example nonlinear). The greatest benefits can be seen for large structures with a large number of linear combinations.
