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.
Each license includes the creation time and the expiration time from our server. From time to time, our application checks the model's change log and if it founds out that the change time is not continuous, it logs off.
For this reason, you should make sure that the system times are continuous. If you make major changes to the system time, log out first.
Yes, you can. Move your mouse pointer over the node and wait a moment. A bubble with the node coordinates will appear.
Yes, you can. In RFEM 5 and RSTAB 8, you can use the cross-sections created with SHAPE‑THIN 8 and SHAPE‑THIN 9.
The Tower Design add-on is still under development. Therefore, it cannot be activated in the Base Data.
If you activate the WebService settings in order to use the RFEM 6 interfaces (Revit, Tekla Structures, Rhino/Grasshopper, Excel via Plugin) and you still get the error message, proceed as follows:
Check the server port range used by the interface. The port range must match the one set in the Program Options of RFEM 6.
The error message remains if the default server port range (8081-8089) is otherwise occupied. Set a different server port range in the Program Options in RFEM 6, such as 10001-10009.
It is also necessary to adjust this server port range accordingly for the respective interface.

The Piping Design add-on is still under development. Therefore, it cannot be activated in the Base Data.
The Harmonic Response Analysis add-on is still under development. Therefore, it cannot be activated in the Base Data.
The Craneway Design add-on is still under development. Therefore, it cannot be activated in the Base Data.
You can hide the undeformed geometry in the Display tab of the navigator by deactivating the Model check box:
In RFEM 6 and RSTAB 9, the calculation parameters are no longer managed in a dialog box of the same name, but in the form of Static Analysis Settings in the Load Cases and Combinations category in the navigator.
There are tree analysis types preset:
You can adjust the parameters of these analysis types or create more types.
In the "Load Cases & Combinations" dialog box, you can then assign the relevant static analysis setting (SA) to the load cases and load combinations.
The Glass Design add-on is still under development. Therefore, it cannot be activated in the Base Data.
The Concrete Foundations add-on for foundation design is still in development. Therefore, it cannot be activated in the Base Data.
The SCIA .xml format is intended for data exchange with RFEM 5. Due to the reprogramming of RFEM 6, the .xml file formats of SCIA and RFEM 6 are not compatible.
A simple solution is to export from SCIA in the SAF 1.0.5 format. This can be imported into RFEM 6.
We usually release a new version of RFEM 6 / RSTAB 9 every Monday; means, four versions per month.
You are informed about a new version on the Extranet and in the Dlubal Center. There you will also find the links to download the versions.
The Timber Joints add-on is still under development. Therefore, it cannot be activated in the Base Data.
The Cutting Patterns add-on is still under development. Therefore, it cannot be activated in the Base Data.
Please note that the enveloping results are usually shown when displaying the results of design situations or result combinations.
There are three options to graphically display the results of deformations, internal forces, and support forces: Max and Min-values can be displayed separately. To display both envelopes from the extreme values on the model, select Max and Min-values.
If you receive an RFEM 6 or RSTAB 9 file for further processing, the structures will be displayed in the program using the display settings of the last editor.
If this display does not meet your own requirements, you can simply right-click the free area of the Navigator – Display and select "Dlubal Standard". This returns the settings to the default values.
If a Rhino surface cannot be created by using the geometry type, it will not be transferred. This is the case, for example, of curved surfaces with more than four boundary lines. In the Rhino command history (_CommandHistory or the F2 key combination), you can find a list of warnings and errors displayed during the transfer process:
