Product Features
Dlubal Software programs and add-ons provide you with a wide range of powerful features. We are continuously developing the software, adding new features, and optimizing existing workflows. We also always have an open ear for our customer requests. Therefore, suggestions and requests from the users are regularly incorporated when we are working on improvements or new add-ons.
In the Geotechnical Analysis add-on, the high-quality material model "Modified Hardening Soil Model" is available. This material model is suitable for a variety of soils and is able to appropriately represent the following properties of the real soil.
- Stress dependence of soil stiffness
- Load path dependence of soil stiffness
- Plastic strains even before reaching the limit condition
- Increasing shear resistance with increasing mesh refinement
- Increasing yield strength with increasing stress until reaching the limit yield condition
- Failure criterion according to Mohr-Coulomb
You can find more information about this material model and the definition of the input in RFEM in the corresponding chapter of the online manual for the Geotechnical Analysis add-on.
In the Dlubal Center, there is an extensive library with connections available for the Steel Joints add-on.
You can access this library directly from the add-on and assign the predefined connections to the corresponding nodes. You can also save user-defined connections in the library in Dlubal Center.
In the Building Model add-on, you can define the design properties of shear walls and deep beams for the respective add-ons.
The "Create surface cells due to openings" option is available to you in the surface shortcut menu. It allows you to easily create the lines for the columns of timber panel walls (using the "Beam Panel" thickness type), for example.
In the Steel Joint add-on, you can arrange plates in various geometry shapes. In addition to the "Rectangle" and "Circle" shapes, the "Polygon" shape is also available. The polygonal shape is defined by entering the point coordinates.
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 the case of 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" type of surface geometry to generate curved surfaces on the basis of control nodes in the middle of the surface.
You can use this option 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 stories, you can use the "Semi-Rigid Diaphragm" option for slabs.
In principle, this modeling option selects the same approach as for the "Rigid Diaphragm" modeling of stories. In contrast to the rigid diaphragm, no nodal coupling is carried out from the center of gravity to each FE node. This way, it is possible to take into account the flexibility of the slab.
In the cross-section program RSECTION, you can generate parts in the corners when creating new elements.
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.
