Frequently Asked Questions (FAQ)
Customer Support 24/7
Except for RWIND Simulation, all Dlubal Software products use the same dongle driver. Therefore, the one-time update or installation is sufficient, for example.
AnswerIn RX‑TIMBER, you can create a user-defined material as a new material in the material library (see the figure), similar to the programs RFEM/RSTAB.In contrast to RFEM/RSTAB, the category is set to "timber" in this case.
AnswerIf this error occurs, the download did not run correctly. Please download the program again. Please note that the file can only be opened after the complete download.
AnswerGenerally, the licensing requires two things:The license key can be provided via a USB dongle or via a network softlock on a central company server. For the licensing from a client, it is necessary to have a permanent connection to the server. Once a license has been assigned, it is visible on the web-based license interface at http://localhost:1947/_int_/sessions.html. The automatic time-out after 12 hours of inactivity prevents the license from being permanently assigned and, releases it to other users.
With the most recent generation of license keys, it is possible to activate 50 licenses for each program and add-on module. This means that you can access RFEM and RF‑STEEL EC3 from a maximum of 50 computers at the same time.

Whether the download of RFEM or RSTAB is displayed or not in the Download section of your Dlubal Account, depends on whether you have a service contract for the respective product or not.If a service contract has been concluded for the respective product, the links for this product are visible.If no service contract has been concluded, no links are visible.If you purchase RFEM or RSTAB without the service contract at a specific time, you are entitled to use this program version. If you need the download link for the purchased program version, you can download it on our homepage in the "Previous Program Versions" section.See the link to "Download Previous Versions" below.
AnswerYes, it is possible. In the "Loads" window of the add-on module, you can modify the loads by using the "Show Generated Loads... or Define Additional Loads..." button (see Figure 01).
AnswerUnfortunately, the calculator implemented in Windows 10 is not compatible with our programs. You can use, for example, the "Copy" option to paste the values into the clipboard and then paste them into the program in order to still use the calculator. A better alternative is to replace the Windows 10 calculator with Windows 7 or Windows 8. There are sufficient instructions on the Internet to carry out this procedure. It is only necessary to make sure that the calc.exe file in the Windows folder C:\Windows\System32 runs the old calculator afterwards. The Windows 7 calculator can then be used as usual after importing the results.
AnswerTo open an RX‑TIMBER file in RFEM or RSTAB, select the "All Files (*.*)" option as "File Type" (see Figure 01). Thus, the geometric data, loads and load combinations will be imported. The settings relevant for the design, such as shear force reduction, fire protection definitions, serviceability limit state parameters, an so on, are not transferred and must be redefined in RF‑/TIMBER Pro.
If the model does not appear in the work window, you can display the view using the "Show Whole Model" option (see Figure 02).
AnswerIn contrast to RFEM and RSTAB, the language settings in the RX‑TIMBER add-on module can be found in Project Manager of the program. You can find the corresponding setting under "Edit" in the menu bar (see Figure 01).
AnswerThe RX‑TIMBER Brace program is generally used for the calculation of the stiffening of double-tapered beams with variable cross-section height. They can be designed in the RX‑TIMBER Glued‑Laminated Beam program.From the RX‑TIMBER Glued-Laminated Beam program, you receive the equivalent loads by beam listed for each load case. The calculation is performed according to Section 18.104.22.168 of EC5. This equivalent load must be transferred to the RX‑TIMBER Brace program for the identical load cases (Figure 01).The axial forces calculated in RX‑TIMBER Brace must be again defined as additional forces in RX‑TIMBER Glued-Laminated Beam. In this case, it is necessary to make a distinction between the compression force in the upper chord of the brace and the tension force in the bottom chord of the brace. Both axial forces must be applied separately. From the tension forces of the bottom chord results a deflection force in the spatial system, which can be applied as an additional moment (Figure 02).

Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
“Thank you for the valuable information.
I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. I have used a lot of software with a support contract in the field of structural analysis, but your support is by far the best. ”
