The structural analysis software RFEM 6 is the basis of a modular software system. The main program RFEM 6 is used to define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members. The program also allows you to create combined structures as well as to model solid and contact elements.
RSTAB 9 is a powerful analysis and design software for 3D beam, frame, or truss structure calculations, reflecting the current state of the art and helping structural engineers meet requirements in modern civil engineering.
Do you often spend too long calculating cross-sections? Dlubal Software and the RSECTION stand-alone program facilitate your work by determining section properties of various cross-sections and performing a subsequent stress analysis.
Do you always know where the wind is blowing from? From the direction of innovation, of course! With RWIND 2, you have a program at your side that uses a digital wind tunnel for the numerical simulation of wind flows. The program simulates these flows around any building geometry and determines the wind loads on the surfaces.
Are you looking for an overview of snow load zones, wind zones, and seismic zones? Then you are in the right place. Use the Geo-Zone Tool to determine quickly and efficiently snow loads, wind speeds, and seismic data according to ASCE 7‑16 and other international standards.
Would you like to try out the capabilities of the Dlubal Software programs? You have the opportunity to do so! The free 90-day full version allows you to thoroughly test all our programs.
The LVL design is carried out with the add-on modules for timber design that are available for RFEM 5 or RSTAB 8.
The following steps are necessary for the design:
Unfortunately, it is not possible to graphically display the results of stresses. They can only be determined numerically in RF‑/TIMBER Pro. This option is available in the add-on module for both RFEM 5 and RSTAB 8.
Line releases are defined by an additional line that is generated by the software. The theoretical background of line releases is described in this Knowledge Base article.
For a detailed explanation of the error, see the model file attached to this FAQ. For the line release No. 3 a definition node has to be set: If the software generated an additional virtual node, Surface 2 would be destroyed.
Imagine the following scenario:
You have four surfaces 1, 2, 10, 14 (see Image 02). When you define a line release to Line 3, it will look as seen in Image 03. As Surface 2 would be destroyed by that (as Line 6 is the same for Surface 2 and Surface 14), Line 6 has to start at Node 3 and at the generated node (see Image 04).
This is where you need the definition node. If it is missing, the software shows the error.
If the import of the current authorization file was successful and the program otherwise runs smoothly, it is not very easy to find an explanation for the problem. Therefore, please send us the "Authorization.txt" diagnostics file. In the programs RFEM 5, RSTAB 8, or SHAPE‑THIN, you can create it using the menu Help → Authorization → Diagnostics.
