Frequently Asked Questions (FAQ)

In RFEM or RSTAB, you can easily display the corresponding support reactions / internal forces in a result combination in tables. This is automatically set by default.If you want to also display them displayed in the printout report, it is necessary to activate the extreme values in the corresponding tables. You can do this in Selection.In this example, the extreme values were only activated for the support force Pz, which means that the maximum support forces in the Z direction are displayed with the corresponding support reactions of the other directions.If you want to include a graphical display, you have to print the graphic of the displayed load cases or load combinations in the printout report.
AnswerYou have probably selected the "Absolute Extreme Value for Result Combinations" option in the Results navigator. Therefore, only the absolute highest value of both is displayed.
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.
In the second tab of the panel, increase the display factor of the "reaction forces." This should improve the display (see Figure 01).
As an alternative, you can adjust the display properties using the menu "Options → Display Properties → Edit": change the size of the display in the "Results → Support Reactions → Nodal Forces" category. If necessary, you can also adjust the "relative limit settings" in the detail settings (see Figure 02).
If you only want to display the "Max" or "Min value" for the RC results, you can make the corresponding setting in the Results navigator (see Figure 03).
These zero values are caused by the superposition type in the combination criterion: if you analyze several load cases or combinations in one result combination and define the load cases as "Variable," then zero is shown for the maximum or minimum value at the locations with the same signs. When using the variable ("eventual") superposition, it can also happen that no load case or no combination becomes effective. Zero is smaller than the smallest maximum value or greater than the greatest minimum value.
A solution would be to define the load cases or combinations contained in the result combination as "Permanent," for example: RC1 = CO1/Permanent or CO2/Permanent or CO3/Permanent or CO4/Permanent
The load cases or combination are then compared as permanently acting. Thus, the obtained extreme values are unequal zero also for the areas with the same signs.
The triangle indicates extreme values of internal forces (figure 1). In the results table of RSTAB and RFEM, these are shown in bold font (figure 2).
Bold font would not be very appealing in the printout report. For result combinations, the table always shows two values: the maximum and minimum.
Yes, you can display the maximum deformation of each member. Go to the "Display" navigator, open the items "Results", "Deformation" and "Members", and activate the option "Show extremes".
If you have changed several default settings and want to reuse them, you can define the complete "Display" navigator settings as the default setting. Just right-click into the free space of the navigator and select "Save Settings as Default" in the context menu.

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. ”
