Frequently Asked Questions (FAQ)

In a 2D model XY with the degrees of freedom (uz/fx/fy), no eccentricity can be defined. The eccentricity usually results in an axial force that is not covered by these degrees of freedom.
You should also be careful when using ribs. In contrast to the 3D model, the effective width also changes the stiffness of the structure.
Therefore, it is generally better to calculate the downstand beam structures in a 3D model.
It depends on the choice of the model type. In this case, a plane system was selected. Thus, the relevant results are displayed even for this plane because they are reduced due to the limited coordinates and degrees of freedom (see Figure 1). However, if you select a 3D structure as the model type, all stresses and internal forces are displayed (see Figure 2).
AnswerYou find this setting in the "General Data" of the model.You can distinguish between the model types "3D", "2D - XY", "2D - XZ" and "2D - XY".If you want to enter a floor as a 2D model, and the axial forces within the slab should not be taken into account, set the model type to "2D - XY". If you want to enter a wall, set "2D - XZ".Find more information in the RFEM manual, chapter 12.2.1 General - Type of Model.
You can define the model type 2D - in XZ (plane) or 3D (spatial) in General Data.
General data of a model can be found under "Edit → Model Data → General Data."
As an alternative, you can right-click "Model Data" in the Data navigator and select "General Data" in the shortcut menu.
The model type can also be adjusted retroactively.

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. ”
