Open SHAPE-THIN as an administrator: Right-click the SHAPE‑THIN instance → "Run as Administrator", see the figure.
As an alternative, you can uninstall SHAPE‑THIN and perform a new installation as an administrator as described above.
The error message shown in Figure 01 is displayed if no material has been defined for the cross-section.
In this case, it is necessary to assign the material to the cross-section. To select a material from the material library, open the library by clicking the "Import Material from Material Library" button and select the material (Figure 02).
The procedure is shown in the video.
The reason for this is that the program allows you to select the materials from valid as well as from old ("invalid") standards.
In the program, the materials are stored with the material description and the standard. When selecting the desired material, it is necessary to pay attention to the material description and the standard to ensure that the selection is correct.
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.
The user-defined materials are available to all users. All users must have full access rights to the path of the user-defined material library.
The user-defined materials are saved in the Materials_User.dbd file. For the standard installation, the file is located in the C:\ProgramData\Dlubal\[Program] [Version]\General Data directory. You can also view the file path in the program options (see Figure 01).
AnswerYes, it is.Open the table "1.2 Materials" and the material library for the reinforcing steel. See figure 01.In this material library you can create a new "user-defined" material and edit the standard presets for example for the yield strength. See figure 02.Afterwards you can select this user-defined material for design in table 1.2 in RF-CONCRETE Members and RF-CONCRETE Columns.It is the same for the RSTAB-modules CONCRETE and CONCRETE Columns.In the settings for the national annex, there are limits defined for the maximum value of the yield strength. See figure 03. To change this limit, you need to create a new user defined national annex. See figure 04.
AnswerThe first option is to reinstall the program. The first time you try to reinstall the program, you will be asked if you want to start deinstallation first. Confirm the query and reinstall the program.The second option is to manually integrate the already existing material libraries from another computer on which the programs are already installed. Thus, the following material databases must be synchronized in each program version:
By default, these databases are located in the hidden folder C:\ProgramData\Dlubal\RFEM\General DataAlso, you can find the material databases for the versions RFEM 5.18 and RSTAB 8.18 under the download links
- Material library 'Materials.dbd' installed by the program together with common materials
- User-defined material library 'Materials_Purpose.dbd'
AnswerThe property of the material masonry depends on a large number of input parameters. It would be very extensive to list all possible combinations. To create a material, click the "Create new masonry material ..." button. Once created, the material remains in the library for repeated use.
The material library can be extended. If you add a new material, you can use it for all available models.
Click the "Create New Material" button in the library (see the figure).
The "New Material" dialog box appears. The parameters of the entry selected in the "Material to Select" list are preset. Now, adjust the values. Creating a new material is easier when you select a material with similar properties first.
The user-defined materials are saved in the Materials_User.dbd file. This can be found in the master data folder of RFEM (C:\ProgramData\Dlubal\RFEM 5.xx\General Data). You can save the file and transfer it to another computer, if necessary.
In each program version, these two material databases must be synchronized:
- The material library "Materials.dbd" with the usual materials installed by the program
- The user-defined material library "Materials_User.dbd"
The following steps can help to solve the problem:
- Open the command line with administrator rights
Image 02 - Command Prompt
- Go to the RFEM folder
- execute the following command:
DBConverter.exe /Material_Synchronize "C:\ProgramData\Dlubal\RFEM 5.23\General Data\Materialien.dbd" "C:\ProgramData\Dlubal\RFEM 5.23\General Data\Materialien_User.dbd"

The paths must of course be adjusted. It takes a little while to complete the process. You can check this by looking in the Task Manager.
Alternatively, a new installation is recommended. The first time you try to install the program again, the program asks if you want to uninstall the program first. Confirm the query and then reinstall the program.
- Open the command line with administrator rights

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. ”
