AnswerIn contrast to the old version, the latest version includes new additions and improvements in the functionality as well as revisions. Therefore, the results of the new version would still not be viewable in the Viewer of the old version.
In general, the functioning of the Dlubal Software program versions is not retrograde. This is only valid for the normal versions for viewers.The best solution is to install the viewer of the same RFEM version on which the results have been saved.
AnswerIn the general printout report selection, it is possible to define the load cases to be displayed, but only for all result types. However, it is sometimes reasonable to differentiate this setting depending on the result type (for example, support forces of all load cases, the resulting internal forces should only be displayed by the governing load cases).On the one hand, this can be set with the special selection per result type (right-click the corresponding entry in the navigation tree).On the other hand, all load cases can remain selected in the general selection, and all unnecessary load case results are then removed manually from the navigation tree.This manual selection can be overwritten in the global settings. The corresponding option "Overwrite Individual Settings" appears here.
AnswerThe reason for this is that no results have been selected. As soon as you activate at least one check box that leads to results, the members will also be displayed.
AnswerIn the results of the RF‑/DYNAM Pro add-on module, "Basic Internal Forces" and "Basic Stresses" on surfaces are only provided. However, you can use the option to export the results in a result combination to display all results after the time history analysis.Simply use this option to create a result combination in the add-on module as shown in Figure 01, and show the results in the graphic. All results, such as "Design Internal Forces" or "Stresses," are available then.
The RF‑/DYNAM Pro add-on module allows you to exchange the following results via the RF‑COM/RS‑COM interface:
- Nodal deformations (Table 5.20)
- Member deformations
- Surface deformations (RFEM)
- Nodal masses
- Effective modal mass factor
Furthermore, the resulting internal forces, deformations, and support reactions of the equivalent load cases can be disaplayed via the RFEM/RSTAB interface. For each of these output options, there are the help files available. These files are described in this article.
AnswerThere are several possibilities to evaluate the results of line hinges:
- Graphical evaluation of the results: Under "Releases" in the Results navigator, you can display various forces and deformations of the line releases in the graphic.
- Display of the results in tables: For the tabular evaluation of the results, Table "4.45 Line Hinges - Deformations" and Table "4.46 Line Hinges - Forces" are available.
- Evaluation by means of result diagrams: You can use the shortcut menu to view the result diagram of the line hinges.
AnswerFor this, the results including the result values on surfaces are very helpful.In this case, the extreme values are only displayed by default. Furthermore, you can specify in the Results navigator whether to display the max/min values of the total model, of all surfaces or solids, or of all local extreme values.
AnswerYes, you can define an area in the panel by clicking the button "options". Here you can define a customized area by moving the slider. In that case the areas with higher or lower stresses have no color.
The design details can be opened in section Serviceability under individual calculations. To do this, the line with the corresponding calculation must be selected and then the info button pressed (see Figure 1). The design details can also be selected in the lower part of the dialog.
AnswerFor volumes, we do not provide any internal forces in the program. The conversion of the Spannnugnen in internal forces would be very complex, since not only mx, my and mz would be present, but also the parts of the drill, mxy, myz, mxz also lateral forces and normal forces. With volume one limits oneself usually on a direct voltage evaluation. If you still need internal forces, you have the option to apply the internal forces of the volume to a rod. For this purpose the result bar was implemented in the program.

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. ”
