Frequently Asked Questions (FAQ)

Line releases are defined by an additional line that is generated by the software. The theoretical background of line releases is described in a Knowledge Base article.
For a detailed explanation of that error, see the model file attached to this FAQ. For the line release no. 3 a definition node has to be set: If the software generated an additional virtual node, surface 2 would be destroyed.
Imagine the following scenario:
You have four surfaces 1, 2, 10, 14 (see Figure 02). When you define a line release to line 3, it will look as seen in Figure 03. As surface 2 would be destroyed by that (as line 6 is the same for surface 2 and 14), line 6 has to start at node 3 and at the generated node (see Figure 04).
This is where you need the definition node. If it is missing, the software creates that error.

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. ”
