Question:
What is the meaning of the symbols in the graphical display of mode shapes of the RF-/DYNAM Pro add-on module?

Answer:
The symbols in the RF‑/DYNAM Pro graphic should indicate the local torsional rotation of members.

Since the members in the graphic are related to the centroidal axis, there is no other way to recognize rotations. For this reason, the display with the short vertical line with the small end circles was selected.

In the animation, you can see that these symbols rotate and thus represent the rotations.
