RFEM and RSTAB models can be saved as 3D glTF models (*.glb and *.glTF formats). View the models in 3D in detail with a 3D viewer from Google or Babylon. Take your VR glasses, such as Oculus, to "walk" through the structure.
You can integrate the 3D glTF models into your own websites using JavaScript according to these instructions (as on the Dlubal website Models to Download).
With the Camera Fly Mode view option, you can fly through your RFEM and RSTAB structure. Control the direction and speed of the flight with your keyboard. Additionally, you can save the flight through your structure as a video.
The direct interface with Revit allows you to update the Revit model according to the changes you have made in RFEM or RSTAB. Depending on the modification, the Revit objects may have to be regenerated (deleting the object and subsequent regeneration). The regeneration is performed on the basis of the RFEM/RSTAB model.
If you want to avoid this regeneration, activate the check box 'Update only materials, thicknesses, and sections'. In this case, only the properties of the objects will be adjusted. Changes different from those in material, surface thickness, and section are, however, not considered in this case.
It is possible to access the TeamViewer directly by opening the Help menu of RFEM and RSTAB. Customers with Service Contract Pro can thus benefit from easy and quick online support via video conference.
When exchanging data with Advance Steel using *.smlx files, the interface is detected automatically. This means that *.smlx files can be created even if no version of Advance Steel is installed.
The member type 'Dashpot' can be used for time history analyzes in RFEM/RSTAB with the add-on modules RF-/DYNAM Pro - Forced Vibrations and RF-/DYNAM Pro - Nonlinear Time History. This linear viscous damping element considers forces dependent on velocity.
With regard to viscoelasticity, the member type 'Dashpot' is similar to the Kelvin-Voigt model, which consists of the damping element and an elastic spring (both connected in parallel).
If you are interested in making your daily work easier and more efficient, you should also pay attention to this feature. Program configuration menus and toolbars can be freely customized. This allows you to arrange your frequently used functions in a user-defined way and save time. Everything from the beginning? No problem: You can restore the default settings of the program with a mouse click. Tables, navigators, and toolbars can also be moved and docked as required.
Furthermore, you can use the configuration manager to set the graphic display properties, toolbars, and so on in a user-defined way and save them as your own configuration. Thus, the software becomes your individual productivity enhancer.
Dlubal Software customers come from all over the world and there are, of course, numerous language options for the structural analysis software. It is possible to operate the program in the following languages: English, Chinese, Czech, Dutch, French, German, Italian, Polish, Portuguese, Russian, and Spanish.
You can also modify the design of the RFEM/RSTAB user interface: There are nine different styles of graphical user interface to choose from; for example: Office 2007 Blue, Silver, Aqua, and Black. Customize the programs to your individual needs.
The Dlubal programs are user-friendly. This way, you will have a short induction period and easy handling of the software.
Your structure is created in a user interface usual for CAD or via tables. By right-clicking the graphical or navigator objects, you can activate a shortcut menu that allows you to easily create or modify the objects. Try it out for yourself and let yourself be inspired by the intuitive user interface! Therefore, you can create the structural and loading objects in a minimum amount of time.
You also have many useful options for printing. You can mass print the model, loads, and results. In this case, it is possible to create graphics from different defined directions. For example, you can print all internal forces as an isometric view with just a single mouse click. This way, you can always keep track of things.
Utilize all the options of the 'Edit Load Cases and Combinations' dialog box to facilitate your work. Here you can automatically create load and result combinations after selecting the corresponding combination expressions. In this clearly arranged dialog box, you can also e.g. to copy, add, or renumber load cases.
Additionally, control the load cases and combinations in Tables 2.1 – 2.6.
Always keep track of things by assigning different colors to the various objects in your structure. Thus, the rendering display of the structure is even clearer; and you can see the essentials at a glance.
You can distinguish between Materials, Cross-Sections, Member Types, Member Hinges, Surface Types - Geometry, Surface Types - Stiffness, Surface Thicknesses, Solid Types, Surface Sides, Named Visibilities, and Effective Length Factors.
To test the program before purchasing an RFEM or RSTAB license, you can download the free 90-day trial version. This will allow you to test the full version of the program without any limitations.

For the European standards (EC), the following National Annexes are available:
The introductory examples and tutorials for RFEM 5 and RSTAB 8 will help you to get started with the program. Step by step, you will become familiar with the most important features. You can download the documents in PDF format.
Extensive cross‑section and material libraries facilitate the modeling of plate and beam structures. These databases can be filtered and expanded with user-defined entries. It is possible to import and analyze special cross‑sections from SHAPE‑THIN and SHAPE‑MASSIVE.
When archiving projects, you can also save other document files from the project folder. Then, the data are compressed in a ZIP file. The advantage is that the archive can be unzipped by programs other than Dlubal Software programs.
The project manager can also manage subprojects. The manager displays the relevant information of each model; for example, the date of creation and latest modification of a structure, as well as the related user name. In addition, you can see the dimensions and weight of each structure. It is possible to restore accidentally deleted projects from the integrated recycle bin.
There is a mass print function for the model data, loads, and results. It is possible to create graphics from different defined directions. For example, you can print all internal forces as an isometric view with a single mouse click.
The first result table displays a summarized overview providing the equilibrium of forces in the structural system and the maximum deformations. Information about the calculation process is included as well. You can filter the result tables by specific criteria such as extreme values or design locations.
The results on a rendered model are represented by a number of colors in order to easily detect deformations such as member rotation. You can freely define the colors and the range of values in the control panel. Deformations, surface stresses, and internal forces can be animated and saved as a video file.
The result diagrams of members, surfaces, and supports are freely configurable: You can define smooth ranges with average values or, if necessary, display and hide the result diagrams. This option ensures targeted evaluation of the results. All diagrams can be added in the printout report.
The result tables show in color whether the internal forces are positive or negative, as well as showing the relation to the extreme values. The result tables of the design modules use color scales to represent the respective design ratios. This way, the governing locations are apparent immediately.
The loading can be applied incrementally. The increment option is especially useful for calculations according to the large deformation analysis. For members, you can consider shear deformations and apply internal forces to a deformed or undeformed structural system. In addition, RFEM allows you to perform post‑critical analyses.
The calculation can be performed for all member types according to the linear static, second-order, or large deformation analysis. This selection option is available for load cases and load combinations. Additional calculation parameters are individually adjustable for load cases, load combinations, and result combinations. This ensures a high degree of flexibility with regard to the calculation method and detailed specifications.
In the individual load cases or combinations, there is the option to modify the stiffnesses of materials; cross-sections; nodal, line and surface supports; and member and line hinges for all or selected members. Furthermore, it is possible to consider initial deformations from other load cases or load combinations.
The load cases included in the result combinations are calculated first. Then, the results are superimposed by taking into account the corresponding factors. In the result combinations, you can superimpose the results of load cases, load combinations, and other result combinations. Internal forces are added together by default. However, there is the option of a square addition, which is relevant for dynamic analysis.
