First Steps with RFEM
Question
I have a model with surfaces and members. If you display the deformations in the graphic after the calculation, the members remain in their original position.However, the members are connected to the surfaces and member deformations are also displayed in the table. Why is that?
Answer
In order to avoid confusing the display, the member deformations are only displayed as lines in the default setting.
In the Project Navigator - Display, you can adjust the display so that the member deformations are also displayed as rendered cross-sections (Figure 1).
Furthermore, it is possible in the "Display" navigator to hide the undeformed model in order to only consider the deformations (Figure 2).

User -defined visibilities facilitate program handling. Once created, any model groups can be quickly hidden or shown. This facilitates, among other things the analysis of the results in larger 3D structures but also the creation of the report. When changing the geometry, the existing visibilities may have to be updated.

Increased Calculation Performance by Reducing the Nodal Degrees of Freedom
The number of degrees of freedom in a node is no longer a global calculation parameter in RFEM (6 degrees of freedom for each mesh node in 3D models, 7 degrees of freedom for the warping torsion analysis). Thus, each node is generally considered with a different number of degrees of freedom, which leads to a variable number of equations in the calculation.
This modification speeds up the calculation, especially for models where a significant reduction of the system could be achieved (e.g. trusses and membrane structures).
