In the "Import Support Reaction" load wizard, the "Free Loads" object connection type is available in addition to the "Manual" ones. This option saves you the task of manually assigning the support reactions to specific nodes and lines. The support forces of the connected model are applied as free loads in this option.
In the Steel Joint add-on, you can arrange objects with a relative reference to other objects.
You can use the "spline with minimum curvature" surface geometry type to generate curved surfaces on the basis of the control nodes in the middle of the surface.
This can be used to model terrain surfaces, for example.
In the result diagrams in the surface point, you can simply select the mesh nodes in the graphic to display the detailed results at this point.
When modeling floors, the "Semi-rigid diaphragm" option is available for slabs.
In principle, this modeling option selects the same approach as for the "Rigid Diaphragm" floor modeling. In contrast to the rigid diaphragm, no nodal coupling is carried out from the center of gravity to each FE node. In this way, the flexibility of the ceiling can be taken into account.
- Numerous component types, such as base and end plates, web angles, fin plates, gusset plates, stiffeners, tapers, or ribs for easy input of typical connection situations
- Universally applicable basic components (such as plates, welds, bolts, auxiliary planes) for modeling complex connection situations
- Graphical display of the connection geometry with dynamic updating during the input
- Wide range of cross-section shapes: I-sections, U-sections, angles, T-sections, hollow sections, built-up cross-sections and thin-walled sections
- Library in Dlubal Center with program template connections as well as user-defined templates
- Automatic adaptation of the connection geometry based on the relative arrangement of the components to each other – even in case of subsequent editing of the structural components
In the Navigator – Results, you can select the design situations for which you want to display the add-on results graphically.
For design objects, you can optionally display sags or extreme results.
You can add dynamic shadows in the rendering mode. In the shortcut menu, you can use sliders to change the main light position.
The "Stub" component is available to you in the Steel Joints add-on. It allows you to extend a member using a purlin joint with another member (stub) and to connect it to a reference component.
In the Stress-Strain Analysis add-on, you can use the option to specify sign-dependent limit stresses by stress component.
In the Steel Joint add-on, you can define several ribs at the same time on one member or plate. The distribution can be carried out according to an orthogonal and a polar pattern.
The material library of RFEM and RSTAB includes the timber materials according to the American standard ANSI/AWC NDS‑2024.
In addition to JavaScript, the Python high-level functions are also available in the console. Using the Python option, the console also provides you with the Python HLF functions known from the WebService function catalog for further use in the object properties dialog box for in-app scripting.
In the Stress-Strain Analysis add-on, you can define a component-dependent limit stress cycle and consider it in the design.
In the Concrete Design add-on for RFEM 6, you can perform the fire design of reinforced concrete slabs and walls according to the simplified table method (EN 1992‑1‑2, Section 5.4.2 and Tables 5.8 and 5.9).
When generating shear walls and deep beams, you can assign not only surfaces and cells, but also members.
Get a better understanding of the stress distribution within member cross-sections by using clipping planes.
In the Concrete Design add-on, you have the option to define an existing vertically oriented punching shear reinforcement. This is then taken into account in the punching shear design.
In RFEM, the oriented strand board (OSB) material is available for the USA and Canada. The material parameters are taken from the "Panel Design Specification manual".
The "Bracing in Cells" function allows you to generate diagonal bracing with just a few clicks. You can find this feature under Tools → Generate Model – Members → Bracing in Cells.
In RFEM and RSTAB, you can visualize the flow field quantities of pressure, velocity, turbulence kinetic energy, and turbulence dissipation rate for the wind simulation.
The clipping planes are aligned with the respective wind direction.
In the ultimate configuration of the steel joint design, you have the option to modify the limit plastic strain for welds.
The "Base Plate" component allows you to design base plate connections with cast-in anchors. In this case, plates, welds, anchorages, and steel-concrete interaction are analyzed.
In RFEM, you can generate surfaces from members with the library cross-sections as well as from the members with the RSECTION cross-section.
You can neglect openings with a certain area in the building model calculation. This function can be activated in the global settings of the building stories. A warning message appears saying that the openings have been neglected.

Use the "Independent mesh preferred" option in the FE mesh settings to create an independent FE mesh for the integrated objects.
This allows you to generate a significantly more detailed and precise FE mesh for individual objects that are integrated into one another.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
In RFEM 6 and RSTAB 9 you have the option to enter Visual Objects as guide objects. You can import the file formats 3ds, stl, and obj.
These objects allow you to create a better reference to the dimensions.
