It is possible to disable displaying the model in the Project Navigator - Display. Then, the loads will only be displayed. Another option is to edit the loads via the table.
The video shows both options on a simple example.
Yes, it is possible.You can "Lock all picture" in the printout report by using the corresponding button in the toolbar.Furthermore, you can select the "Lock graphic picture (without update)" option directly when printing the graphic into the printout report.A graphic already contained in the printout report can also be locked retroactively. To do this, right-click the graphic and open "Properties ..." In the "Graphic Printout" dialog box, you can select the "Lock graphic picture (without update)" option.The locked graphics are indicated by a small lock symbol in the navigator of the printout report.
We have received a NET softlock and activated it successfully on the license server. However, after the installation of the programs on a user's PC, the "Authorization" dialog box appears when starting the program. If I select the "Use full version" option and refer to the authorization file, I get a message saying that the license has already been activated. What should I do?
AnswerIf there is no authorization file already being used on the computer, the program tries to reactivate the softlock. Since this is already active, the corresponding message appears. There are two ways to apply the already activated license to the clients.
- Select the "Use demo version" option in the "Authorization" dialog box and load the authorization file as follows: Help → Authorization → Load Authorization File
- Rename the AUTHOR.ini file to AUTHORE.ini and save it in the directory C:\ProgramData\Dlubal\Global\General Data.
First, the impact load if defined as a load case in RFEM or RSTAB. This load case is then considered in a load or result combination, for which the support forces are determined.
In the design, RF‑/FOUNDATION Pro always uses the support forces from RFEM or RSTAB. This applies for all designs and cannot be controlled separately.
It is only possible to completely deactivate a certain support force for the designs.
Figure 01 - Deactivating Support Loads for Foundation Design
If you do not want to consider a load for geotechnical designs, for example, because the foundation is otherwise constructively stabilized with regard to the impact load, it is possible to deactivate the load in the setting shown in the figure.
However, if it is necessary to consider the impact load for bending design (for example, design of bucket walls), you should copy the design case and include the impact load again.
The foundation evaluation would then be performed using two design cases in the module.
AnswerIn RFEM 5 and RSTAB 8, there is the option to assign various stiffnesses to the individual objects, such as nodal supports, by load case. This feature can be found in the calculation parameters of the load cases and load combinations (see Figure 01).
In RFEM 5, the individual objects can also be deactivated by load case (see Figure 02).
The tab allows you to ignore certain objects of the model in the calculation. In this way, the effect of temporary members (construction supports) or supports can be analyzed, for example.
AnswerThe RF-DYNAM Pro - Nonlinear Time History Analysis add-on module is only available for 3D models. So you have to change over to "3D" in the model's general data.
I have a foundation kept in one direction (X- or Y-direction) by connected ice walls (tie beams). From the determination of internal forces in RFEM, I get the horizontal support forces in the X- and Y-direction. This is correct. However, the foundations in the X‑direction are supported due to the ice walls. Is it possible to 'switch off' or neglect the support reaction from RFEM for the foundation design in RF‑/FOUNDATION Pro?
AnswerYes, it is possible.You can find the control in the design details of the respective design case in RF‑/FOUNDATION Pro.On the one hand, you can select the support load (Px, Py, Pz, Mx or My) that should not be considered in the design. On the other hand, you can also determine whether the forces or moments should be deactivated for a specific direction only or for all directions.However, it is important that the deactivation of the support load is effective for all designs of the design case. If the support load Px should only be deactivated for the design of sliding, but not for all other design, you can control this by creating two design cases.
AnswerThis option is also available in RSTAB for members. This option can be activated in the "Calculation Parameters" of a load case under "Modify Stiffnesses".
AnswerIn the definition of the beam geometry in mask 1.2, the option 'Vertical Stiffeners at the End of the Beam' is activated by default in the tab 'Stiffener'. Proceed as follows:
Now the suspension crane can go beyond the beam ends.
- In Mask 1.2, open the 'Stiffener' tab and deactivate the option (Fig. 01)
- Now you can deactivate the stiffeners in column K in the 'Supports' tab (Fig. 02)
- In mask 1.4 'Loads', the girder buffers can now be deactivated (Fig. 03)
AnswerPlease disable a softlock as follows:
- Download our deactivation tool. http://download.dlubal.com/?file=DeactivateLicense.zip
- Unpack the ZIP archive on the PC with the active softlock
- Start the tool by double-clicking on "DeactivateLicense.exe".
- Select the softlock to be deactivated and press "Deactivate"
- Send us the *. * Ack file created after deactivation.

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. ”
