Add-on Modules



When determining the RF-STABILITY buckling modes, additional lines are displayed for each member perpendicular to the buckling curve. What is it all about?


These lines represent the local torsion rotation (see Figure 01). By default, only torsion rotations φx with normalized values greater than 0.2 are displayed. This ensures clear arrangement of the graphic. The graphical representation is controlled directly in the add-on module (see Figure 02).
