Eigenfrequencies of a Cable

This example shows how to get the eigenfrequencies of a prestressed cable under dead load. For this it is important to know the self-loaded deformation - thus a form finding (via reduction of stiffnesses) has to be done. Hereupon the eigenfrequencies of the cable can be calculated.You will find the input data file viaTEDDY > help > examples... > ase > english > geometric_nonl > cable_eigenfrequencies.datLevel of difficulty: beginners
