• ### How can I automatically generate result combinations?

In RFEM and RSTAB, you can automatically create combinations according to various standards. In the case of a purely linear calculation, the generation of result combinations can be defined in General Data of the model. The attached video shows the automatic generation.
• ### When generating the FE mesh of an ETFE cushion, some problems occur. I cannot find any mistake. What can I do?

In most cases, the problem is that the finite elements of the cover surfaces are very close to each other in the edge area of the cushion when using Bézier surfaces. The FE mesh nodes of the bottom and top surface might be combined then. In principle, there are two approaches:

1. Numerical solution of the problem:

You can adjust the tolerance for combining FE mesh nodes by using the menu "Tools" → "Regenerate model."

2. Geometrical solution of the problem:

A more workable solution is to increase the distance between surfaces by using the boundary surfaces as shown in Figure 01.
• ### Is it possible to generate an FE-mesh with elements that have more than four nodes?

No, unfortunately that is not possible. A finite element can only have three or four nodes.
For further information regarding basics of finite elements in RFEM please take a look at our RFEM-Manual, chapter 7.2.1 - Basics of Finite Elements in RFEM.

#### First Steps

We provide hints and tips to help you get started with the main programs RFEM and RSTAB.

#### 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.

#### Your support is by far the best

“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. ”
