CYPE 3D

Up until now, the "Pin ends" tool in the "Bar" menu only allowed users to pin one or both ends of each bar individually.

As of version 2025.c, this tool has incorporated an option for selecting multiple bars, which automatically pins the two ends of all selected bars.

This selection can be carried out one bar at a time, using a rectangular selection area or using the new filtering tool, which makes the process considerably easier when the ends of multiple bars need to be pinned.

The linear buckling analysis is carried out for each combination by eliminating the non-linear elements that are not involved and transforming those that are involved into equivalent linear elements. In this process, when two bars with "Only tension" behaviour form a braced frame and both bars are compressed in the same load case, the program transforms the behaviour of these bars to linear and reduces their axial stiffness by half. In situations where a portal frame is braced by two non-intersecting braces if both are compressed in a load case, the program deletes them before carrying out the buckling analysis, so the results of the buckling analysis are obtained without considering these bars in tension.

From version 2025.c, with this new tool, bracing pairs can be defined. If both bars in tension in a pair are compressed in a load case, they will be retained in the buckling analysis, reducing their axial stiffness by half, similar to the way the program does it automatically for bars in tension forming a braced frame.

Up until version 2025.c, loads were always represented with a size proportional to the load value. In CYPE 3D version 2025.c, another option is implemented to represent loads with a size proportional to a fixed value.

When the values of the loads are very different, the representation proportional to the value of the load may cause some loads to look very large and others very small. In these cases, this new option is very useful, as it allows a uniform representation.

In version 2025.c, the option to display loads with fill has been added. This feature is available in the dockable panel "View options".

When the option is deactivated, the loads are displayed in the same way as in previous versions. When enabled, the loads are drawn as filled, using the identifying colour corresponding to the loadcase.

When using any tool in the program that requires selecting elements, this can now be done automatically using filters. By clicking on the "Select by filter" option or by using the keyboard shortcut "Ctrl+s", a panel appears where users can define the filters they wish to apply.

At the bottom of the panel, the following options can be chosen:

• Select or deselect elements.
  
  
• Apply the selection or deselection action to elements that meet some or all filters.
  
  
• Reverse the selection.

This tool will significantly facilitate the use of the program. Some of the tasks that can be carried out with this function are: selecting all the bars of a specific section to modify that section, selecting all the vertical bars to adjust their buckling coefficients, or selecting all the nodes that are not connected to any bar to eliminate them, among other possibilities.
