We provide hints and tips to help you get started with the main programs RFEM and RSTAB.
I can't make the predeformations in FE-LTB visible in the rendering mode.
I see either the undeformed system or the stress distribution, but never the predeformation!
To make the predeformations visible in the rendering mode, click the [Select Imperfection] button in Window 2.3 (Figure 1).
The RSTAB work window appears. In the navigator, you can see, which imperfection is currently displayed. By means of the option buttons, you can graphically view the first 10 imperfections (Figure 2).
You can view the individual imperfections also in the rendering mode and even animate it. For the rendering, the same function is available as in RSTAB. After the calculation in FE-LTB, you can click [Graphics] to display the stress distribution, the design ratios, internal forces, deformations, and the used imperfection in the rendering (Figure 3).

Your support is by far the best
“Thank you very much for the useful information.
I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. In the industry of structural analysis, I use several software including service contract, but your support is by far the best.”
