AnswerThe "Connect Node and Element" function allows you to connect the unconnected cross-section parts that are at a certain distance from an element. The connection is made by using an element with a zero thickness. This feature is available in the menu "Edit" → "Connect Node and Element."
AnswerElements are connected together if you have a common node. Thus, Elements 1 and 2 shown in Figure 01 are connected by Node 2.
If there is no common node available, you can create a shear-rigid connection by using a null element. In the case of the null element, the normal thickness t is equal to zero. However, the shear thickness t* must be greater than zero. Determination of the shear thickness t* is required for the null elements that are not affected by "normal" elements (t > 0) along their entire length. It is recommended to specify the thickness of the thinnest element adjacent to the null element.
A null element can be defined manually or created by using the "Connect node and element" function. Please make sure that the connection is always created by using nodes of the elements and not help points (see Figure 02).
If connecting the elements with cross-sections, the cross-sections have to be previously reduced into the individual elements by using the "Reduce Cross-Section into Elements" feature (Figure 03). This is also demonstrated in the video.

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. ”
