In RFEM 5 and RSTAB 8, you can view detailed information on the currently used license and installed dongle driver. In case of any problems with the license, you can send the created text file to the Dlubal Software hotline, which allows us to provide you with a fast and efficient analysis. To create the file, select "Help" → "Authorization" → "Diagnostics".
The same structures are often needed in several projects, such as the purlin with columns and braces in this example. The dimensions can be changed directly in RFEM or RSTAB by shifting the nodes.
Using the Timber Design add-on, timber column design is possible according to the 2018 NDS standard ASD method. Accurately calculating timber member compressive capacity and adjustment factors is important for safety considerations and design. The following article will verify the maximum critical buckling strength calculated by the Timber Design add-on using step-by-step analytical equations as per the NDS 2018 standard including the compressive adjustment factors, adjusted compressive design value, and final design ratio.
The Geotechnical Analysis add-on provides RFEM with additional specific soil material models that are able to suitably represent complex soil material behavior. This technical article is an introduction to show how the stress-dependent stiffness of soil material models can be determined.
The results of solid stresses can be displayed as colored 3D points in the finite elements.
Using the "Beam Panel" thickness type, you can model timber panel elements in 3D space. You just specify the surface geometry and the timber panel elements are generated using an internal member-surface construct, including the simulation of the connection flexibility.
You have the option to perform the fire resistance design of surfaces using the reduced cross-section method. The reduction is applied over the surface thickness. It is possible to perform the design checks for all timber materials allowed for the design.
For cross-laminated timber, depending on the type of adhesive, you can select whether it is possible for individual carbonized layer parts to fall off, and whether you can expect increased charring in certain layer areas.

Among others, the following cross-laminated timber manufacturers are available in the layer structure library:
- Binderholz (USA)
- KLH (USA, CAN)
- Kalesnikoff (USA, CAN)
- Nordic Structures (USA, CAN)
- Mercer Mass Timber
- SmartLam
- Sterling Structural
- Superstructures listed in Lignatec Edition 32 "Cross-Laminated Timber of Swiss Production"
By importing a structure from the layer structure library, all relevant parameters are adopted automatically. The library is continually updated.
When exporting to Excel, I get the error message "Microsoft Excel is not installed on this computer" although Excel is installed. Why?
How can I display the internal forces in the global coordinate system and not in the principal coordinate system of the cross-section?
What is the critical load factor and how is it possible to determine it?
The information about the limit time for the fire resistance design R in the RF‑TIMBER Pro add-on module is missing in the printout report. Is it possible to add this information to the printout report?
The Project navigator has been moved to another screen and I cannot manage to display it again. What should I do?
Can I define surfaces with any number of boundary lines?
