我们在这里为初学者提供了重要的提示和建议，以便用户更加容易快速的掌握使用我们的基本软件 RFEM 和 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).
