Frequently Asked Questions (FAQ)
Customer Support 24/7
It is always necessary to pay attention to the member orientation and member rotation when defining the columns consisting of several single members. Some members have the x-axis directed upwards or rotated (see Figure 01). Due to different orientations, the sign changes for My or Mz.You can easily check these settings by activating the display of member axis systems (see the figure).
AnswerYes, it is possible.You can define the rotation about the Z-, Y-, or X-axis by selecting 2 or 3 nodes. Find the corresponding command button to the right of the text box for the rotation angle. See Figure 01.If you have entered a member that is rotated about its own axis (for example, a purlin on an inclined roof), you can import the "Member Rotation ß" to the rotation of the nodal support. See Figure 02.
The trigger for this is due to the member rotation of a member. A member rotation can be defined in RFEM and RSTAB using two options:
- Option 1: Rotation via angle
- Option 2: Rotation via help node
AnswerFor structures with many arcs, if the coordinate systems of the members are not consistently the same (see Figure 1 -> right model), you can very easily perform the member rotation or the line rotation with a help node.
Right-click the line or the member. In the shortcut menu, select the "Reverse Line Orientation" or "Reverse Member Orientation" option (see Figure 01).
Rotation of the line or member axis system is possible by using a rotation angle, which you can define in the "Edit Line" or "Edit Member" dialog box (see Figure 02). As an alternative, you can orientate the member to a help node.

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. ”
