AnswerThe load case descriptions, load case numbers and also units can be hidden in the 'Project Navigator - Display'.
AnswerIf identical settings are defined in the main program, the missing consideration of the material-related partial safety factor in the load case is often the reason (Figure 1).In the RF-/STAGES module, all calculations are always carried out, taking into account the partial safety factor. If not considered, it must be set specifically for the material.
You can adjust the column individually according to your needs.
Go to the toolbar and right-click in the empty gray area. Then, go to 'Customize'.
Now, click the Load Case Description window and it will be highlighted in black.
Now you can go to the right edge of the window and extend it.
To adjust the column width individually, right-click the empty gray area in the toolbar. A shortcut menu appears. Select the "Customize" function.
Now click on the display field of the load case description. It is highlighted in black. Move the mouse to the right edge of the field until arrow symbols appear on the cursor. You can now drag the input field larger (or smaller).
AnswerWhen defining non-linearities, for example, failure of support under tension, it may happen that some load cases cannot be calculated. If these are loads that cannot exist without other stabilizing loads, solving the problem is simple: You can set the load cases to 'Not To Be Calculated'. As a result, only the load combinations are considered in the option 'Calculate All' of the calculation process. This is possible because, for example, some loads can never appear without having a self-weight.In the attached example, it is clearly evident that the system would buckle in the load case wind, and thus no convergence is found. In contrast to this, it is possible to calculate the load combination in which self-weight and wind are combined without a problem because the self-weight stabilizes the system.
AnswerIn the general printout report selection, it is possible to define the load cases to be displayed, however, only for result types. Sometimes, however, it makes sense to differentiate this setting depending on the result type (for example, support forces of all load cases, internal forces should only be output 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 load from the form-finding load case (FF) is impressed 1.0-fold into the system. If you want to factorize the dead-load in combination with combinatorics, it is possible to additionally create a permanent load case for the dead-load with a load of 0.35 times the load.
To access this function, select Tools - Renumber - Move. This is shown in the attached video.
An automatic transfer to all load cases or load combinations is not possible. However, it is possible to save the user-defined settings and import them in other load cases.To do this, it is necessary to open the dialog box for editing the value and color scales and carry out the user-defined settings. These settings can then be saved with "Save ...".This value scale is now available in all load cases and combinations and can be selected.
AnswerYes, that is possible. In the input window 'Loads' of the add-on module, you can modify the loads by using the 'Show Generated Loads...' or 'Define Additional Loads...' button (see Figure 1). oder Zusätzliche Lasten definieren" Änderungen zu den Lasten vorgenommen werden (siehe Bild 01).

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 very much for the useful information.
I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. In the industry of structural analysis, I use several software including service contract, but your support is by far the best.”
