In the detail settings of the respective result beam, you can specify which objects (members, surfaces, or solids) are to be considered by this result beam.
If, for example, For example, if an unexpected result is displayed for the result beam, you should check in this dialog box whether the integration area has been set correctly for the treated objects.
In the details of all add-on modules, you can control the display of the result tables. In this case, it is helpful to display the results only by load case or by material.
In the RF-STEEL Surfaces module, it is also possible to perform a calculation of only enveloping values.
Furthermore, it may be helpful to display the results in grid points. For the RF-LAMINATE add-on module, it is also possible to completely hide the results of the grid points. You can find a more detailed description here .
The settings for the RF-STEEL Surfaces module are shown in Figure 01.
Yes, it is possible.
The result tables show in color whether there are the positive or negative internal forces and what is the relation to the extreme values. The negative values are symbolized by red bars, the positive ones by blue bars. Thus, the table also allows for a visual evaluation of results.
The result tables of the design modules use color scales to represent the respective design ratios. In this way, the governing locations are apparent immediately.
AnswerPlease check if you have accidentally docked the panel at the bottom of the screen.
If this is the case, you can undock the panel as shown in the video.
AnswerProject Navigator - Results provides a special option to evaluate the results of the RWIND Simulation loads: Activate the results of "Distribution of load" and then select the "Wind load using RWIND Simulation" option.
Regarding the analytical calculation of SLS, you should note that the calculation is based on a provided or applied reinforcement for SLS.
The provided reinforcement can result, for example, from the ultimate limit state design, the defined basic reinforcement, or the automatically determined required reinforcement for SLS. The reinforcement applied to the SLS design can be displayed graphically.
If there are too small or no reinforcement results from ULS or the basic reinforcement in some areas and no required reinforcement is determined for SLS at the same time, the serviceability limit state design is performed without or with too small reinforcement. In this context, very high results may occur during the deformation, for example. Also, there may be poor convergence.
It is necessary to ensure that there is a reinforcement in each area of the structural system. For this, you can apply a basic reinforcement or a minimum reinforcement, for example.
If load cases are superimposed manually, the "Edit Load Cases and Combinations" dialog box only provides three options. This is specified in the "General Data" dialog box.
If you select the "Create combinations automatically" check box, you obtain the additional options (actions, combination expressions, action combinations) as desired.
In this case, you have defined an RF‑DYNAM Pro case and the results are not available. There are two ways to solve the problem:
- Open the Calculation menu and select "Calculate All."
- Select the RF‑DYNAM Pro add-on module and only calculate the results of it.
Now, you can perform the design again in RF‑STEEL EC3. The RC previously shown in red can now be found under "To Design."
AnswerThe calculation of the results in grid points is important for displaying values on surfaces, among other things. You can find the information about grid points here.The problem is that in the case of complex structures and many load combinations, the calculation in grid points is relatively time-consuming and therefore, it requires a large amount of memory. Even if you perform the calculation in FE nodes as shown in Figure 01, it is always necessary to additionally perform the calculation in grid points. Otherwise, the results cannot be displayed in grid points under Values on Surfaces.For complex structures, it is recommended to deactivate this option to perform a faster calculation.

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. ”
